You say that like it's the first time
When windows 11 is clearly the next giant F up in a long series of humiliating walk backs going back to what, Windows Millennium Edition? Windows 3.0?
The only difference is they skipped an number, so the whole odd/even thing is flipped. Windows 11-8-vista-XP(home)-and ME vs Windows 98, 2000, XP Pro, 7, and 10. So since y2k they are stuck at 50% rate of humiliating failure.
They are consistent though right?
People will rightfully howl about this, and there will either be a walkback or yet another registry key to set to turn the bleeping ads off, because like the failed vista and 8 rollouts, there are very big accounts that will tell their M$ rep to shove it and skip the release cycle until/unless it is fixed.
What probably isn't going to happen is a mass of users jumping ship for another OS. Because people don't use windows to do their job. They use software. They will use the version of windows that interferes the least with them using that software to do their job, but most businesses are still locked into windows.
Stay calm and just keep complaining about the problems in 11. In the mean time stay on an LTS build and just wait them out. They need our money more than I need a new operating system, so they need to come to the table with something I want, not something I hate.
