On that regard the public rage is something I don't mind. I don't know what would be enough to modify the value proposition to the point that the core product would be the most important thing in generating shareholder value.
Then again part of this whole thing is exactly to reduce the dependency of ads in how revenue is generated so if the community completely shuts down the effort things are not any better.
But it should never be possible to be in a situation where the costs are as unpredictable as they are in the released model.
You're free to believe what you want, but your message does seem to just repeat points made by YouTube videos that also get a lot of things wrong.
For your main point, the merger with ironsource didn't modify power dynamics in the company that much. Also trying to group an organisation with thousands of employees into a single entity that doesn't care about anything but pushing ads is just ignorant. Maybe you can make the argument for the highest level of the organization that's responsible of generating shareholder value, but I assure you the majority of the company is made of people who actually care about the engine, the community and often are developers themselves.
