Obviously the details matter, and many things happened all at once.
For example, the original policy was going to force out all free open source clients, and that was later retracted, but the damage to the company's reputation was already done.
For example, clients for the visually impaired could have been set aside as a special case immediately, and they weren't, and as I understand it they still aren't.
For example, third-party clients that don't show ads could have been blocked without restricting third party clients that assist mods.
For example, the result of the blackout could have been some sort of sympathetic statement, but instead it was the hammer getting laid down, leading to even worse results.
So you're a question is whether the outcome would have been different if the administrators had acted differently, and of course the answer is yes. That being said, what we've learned is that the administrators do not value the mods or the end user. All of the above issues simply don't matter to them because they don't care.
You talked about capitalism as if it's inevitable, but you're wrong. The decision to try to make a lot of money was made, many other online services have made other decisions, and you don't get to excuse the actions of anyone in the administration on the grounds that it's just the natural consequence of capitalism.
