Don't believe it? Remember Microsoft? They used to dominate our industry and crush innovation. Their tactics made Uber's seem soft and fuzzy. Sure the government gave them a knock but that didn't slow them down. Do you know what did? Apple and iOS. They missed the boat on mobile and now they're still valuable but not an existential threat to the industry.
It's really hard for a tech company to dominate over the decades. Apple has been near death multiple times in the past and while they have a ton of money, they aren't exactly innovating anymore. It will happen again, it's in their DNA.
Facebook is just Myspace 2.0 that was smart enough to snatch up Instagram (starting to show its age), and Whatsapp. Acquisitions != innovation.
None of these companies are threats to technological progress in the long term. Something new will show up a that disrupts their entire model. It's happened with every boom cycle in tech history.
The trick is to look for the next big thing and ride the wave and not look to the single most regressive institution in existence (the government) to come help you.
