In the developer space, it seems pretty much the same. SourceForge was good/cool until it wasn't, so people moved to Github. Now, as Github perhaps gradually loses steam or coolness (might not happen either), another company will emerge (maybe it's Gitlab) who will take share while Github perhaps spins into irrelevance. Wash, rinse, repeat - but each time the software tends to get cheaper and cheaper, creating a massive deflationary environment as the particular developer tool set becomes commodity.
Or maybe AWS or Google step in with an actual good product (hasn't happened yet as far as I can tell in CI/CD but hey you never know), and they charge nothing for it because it's part of a basket of services. Margin for the standalone company goes to zero.
Developers have, as far as I can tell, almost zero brand loyalty - and that probably makes sense - but it's very tough in my opinion to create great products for developers and make money as a company at the same time.
