Yes, network effects, as discussed in the Wikipedia article linked above. It's the reason why Facebook or Twitter are so hard to replace, or eBay, or Amazon. In these cases larger platforms benefit from the fact that everyone else is already there, which makes switching hard. That doesn't mean they are inherently better though. They can even be significantly worse than alternatives, apart from network effects.

Part of the reason why these companies are still around and strong is because they continue to innovate. Facebook spun up Instagram for younger folk, Amazon has some of the best shipping/warehousing/distribution in the world. eBay has slowly become less relevant for local p2p purchase because its market share got eaten up by Facebook Marketplace.... Twitter had a big chunk of its userbase eaten up by Threads, hey I'm seeing a pattern here?

Ascribing my entire comment to network effect makes me wonder if you even read it.
