Does anyone actually believe this is an authoritarian attempt to squash speech that is "speaking truth to power"?
This is the result of years of work to remove any dissenting voice from the generally Left-leaning sites of the Internet -- Twitter, YouTube, Reddit, etc. First they started disabling comment sections, calling all opposition "trolls". Then they tried to deplatform, go after advertisers, etc. Most recently, two sites were dropped from AdSense because they had unmoderated comment sections. Not only is Google saying what can live on it's platform, but also what can live on the sites of others.
But wait...they're a private company and have every right to remove people from their platform. Fine, then they lose all government protection from the results of their choice to decide what legal information people can and cannot see.
