I wonder if there are other " genericized trademark" companies that have failed that spectacularly. You can still buy Frigidaire refrigerators. Vaccuuming is known as "hoovering" in the UK, and Hoover is still around.
It would be pretty interesting if "a GoPro" exists as a word for an action camera and the company / brand no longer exists.
Google and Meta aren't controlling propaganda. They're just trying to make ad dollars.
Propaganda is something you lose money doing, because you're spending money (or using influence) to change minds.
