Without the population on your side, it's some insignificant minority's words vs. corporation's power determining where the lines get drawn by regulators. The people can put a leash on politicians who cave too hard to corporations by voting them out of office, but if they don't even understand the issue and have been conditioned to accept age verification, that will never happen.

I am confused as to why you suggest my view is US-centric, and then go on to acknowledge that the EU is currently in the midst of rolling out regulation that de facto enshrines the Google+Apple duopoly in law. The EU bureacracy seems to be just as captured by corporate interests as the US. At times, they put up a token protest against Apple/Google, but generally only insofar as to promote competing European corporate interests where applicable. The EU would certainly prefer to serve European corporations over American ones, but the European people don't seem to factor into the equation at any point.
