You're complaining about the product quality and trying to compare it to the market leaders in Dota 2. I find this comparison simply unacceptable and absurd. Do you even know the history of how these current "ambassadors" came to be? Probably not. So let me give you a brief overview.
A long time ago, there was only one product - many remember it as Ensage. Around the same time, Hake appeared and became its direct competitor and killer. Ensage was an unstable, laggy piece of crap with constant bans and zero protection. Hake, on the other hand, was extremely reliable, smooth, and never had a trail of user bans because the software had proper protection.
One of those you're using as an example - namely UC - was already back then reaching for Ensage to make money off it. I'm talking about dubstep and his crew. I'll skip the Ensage part - it's not that important. Let's get back to Hake instead.
At the beginning, the same dubstep and his company initially appeared here as enthusiasts, trying to help develop Hake. At some point, they decided their work should be paid, and they approached Stephanie with this question. The answer was simple: "Want to earn? You can resell our product at a higher price. Everything above our price is yours."
I don't know if they did that or not, but they came up with a brilliant business plan: Why develop a product you don't own when you can make your own? Around 2017-2018, they found someone who, for a substantial sum, cracked Hake. That's how the famous Xenohack was born, owned by the current UC team.
Aggressive marketing began, misleading people by selling a crack, and parallel scamming naive fools through Dotameet. Dubstep and his company survived on the crack for a long time, and their inability to fix things meant that after each update, they had to wait for Stephanie to update Hake, then crack it again to "update" their Xenohack. Sometimes it got absurd - their users would wait 2 weeks for updates.
Over time, their users started encountering the real Hake more often, and gradually realized they were being sold a poorly working fake. If I'm not mistaken, in 2018 dubstep and his company finally decided to stop constantly cracking Hake and made "their own" cheat called Umbrella (UC). The funny thing is, their creation was built entirely on Hake's source code (from their crack).
For years, they developed it, built a team, and grew their audience through aggressive advertising. Advertising is the engine of progress - can't argue with that. Have you ever seen Hake advertising anywhere? I personally haven't. Only mentions on various forums from regular users.
The second "ambassador" - M - is also built on UC sources, by the way. Their old coder and cracker, Arting, betrayed them and sold out. Yes, in 2019, UC's coder dumped them and leaked the project to M.
The bottom line is this: without Hake, both current Dota 2 market ambassadors simply wouldn't exist. They're both cracks that grew into huge projects due to aggressive marketing.
Now let me explain why your comparison isn't fair. UC and M have huge staff. Multiple core developers, tons of scripters, media personalities. They have a massive team that gets paid salaries. Hake currently has only 1 developer - Stephanie. No advertising, no media, no staff of scripters.
What kind of consistency are you talking about here? What stable and constant script updates? All scripters here are enthusiasts, nothing more. While they were interested, they posted stuff here quite frequently and consistently. The enthusiasm ended, and they left the forum, abandoning their scripts to die. Some left Dota 2, while others joined UC and M staff for regular salaries.
Why do you think another person should spend their time and effort on work (creating scripts IS work) completely for free? Do you work in real life? I don't think you work for free and enjoy it. No, you get a stable salary for your work. Let me repeat: writing scripts is the same kind of work that should be paid.
Let's go back to Ensage for a moment. They also had their own script marketplace. People paid money for Ensage subscription + one-time payments for scripts from private authors. I'm applying the same model here, since the Hake administration directly stated that selling your own scripts here is not prohibited. I think the administration also understands perfectly well that script authors want to earn some income for their work.
The administration's job is to keep the cheat updated and current for game patches - nothing more. That's exactly what you're paying them for with your subscription. Scripts are the scripters' work, but since there are no staff scripters, you get a situation with tons of dead scripts from enthusiasts. Your criticism is superficial and you haven't delved into the details at all.
Regarding cleaning up the forum - I'll agree with you here. Removing outdated and broken scripts is indeed necessary. Maybe even conducting some forum reform. The forum is indeed a big mess. However, all this requires a colossal amount of time, effort, and desire, which Stephanie probably just doesn't have at the moment. From what I can see, the current active staff is 2 people. Frog as support specialist, and Stephanie herself, who handles the forum, servers, software, updates, API, and much more. There was also kawaii, but I don't know if he does anything, given that his last forum visit was 2 years ago.
