Google wanting things, (ab)using their position as the most popular browser to get an implementation out there before there is a standard, then getting surprised that others don't want it. FLoC all over again.

Thank you for the reply, I was kindof expecting that this would play out as such. I am very excited for the future of browsers and web protocols, but some of them are so exclusive and heavy-handed by Google that I worry.

Google needs to continue their developer relations efforts. I think they want to be on the same team as "us", from a technology perspective. Perhaps if only for the sake of adoption.
