Yup also called the "phoenix effect" or "entrepreneurial recycling" or "second-wave innovation".

Not FOSS necessarily but you will see lot of new startups exploring new niches.

We saw it after the dotcom bubble burst, 2008 GFC, Cryto/NFT implosion 22-23 (shifting people to AI).

FOSS is mostly big tech funded these days. They use some library long enough, get dependent on it and then end up assigning funds for maintenance. Or the other way round where they build something internally - run out of budget to keep it running - open source to community.
