The much maligned “Trusted Computing” idea requires that the party you are supposed to trust deserves to be trusted, and Google is DEFINITELY NOT worthy of being trusted, this is a naked power grab to destroy the open web for Google’s ad profits no matter the consequences, this would put heavy surveillance in Google’s hands, this would eliminate ad-blocking, this would break any and all accessibility features, this would obliterate any competing platform, this is very much opposed to what the web is.
Firefox will most likely support this, if it doesn’t want to get cut off from most of the web.
However, it would be nice to have a Firefox or Chromium fork with a switch to disable the “feature”, an option to remove any links to websites requiring this stuff, and some search engine free of links to websites requiring it.
However non technical folk will not be able to or really be interested in all that and will just download the regular browser and leave the option enabled. This only gets traction if the option it turned off by default.
