Again, these changes aren't taking place until 2023. They are still accepting new features. Yes, everyone is aware that the developer of uBlock threw a fit. It was all over the news, and it was portrayed by the media as Chrome is disabling adblock, because that is essentially the message from
Raymond Hill at the time. I think it is good to be aware of these changes, and contribute feedback and try to get compatible or comparable APIs implemented. At no point has Google or Chromium said they are unwilling. If anything, it looked like a prime opportunity for them to scream fire when there was no fire.
