> startups with 10+ years of unprofitable existence without any potential exit are going to get disrupted by newer players.

It depends how unprofitable. Well-established products like Twitter and Reddit are big, have an established user base, and while not particularly profitable, I also don't see them getting disrupted by a rising competitor.

They are social media sites, the textbook example of the network effect.

Them not being very profitable is almost like a moat in itself - not only is it hard to displace them, it's probably not profitable to do so either.

Mastodon — which is a non-profit — is nibbling away at Twitter.
