So why don't we see more startups use open protocols for access to email rather than make things that are GMail specific?

Why do you get voted down for just suggesting that they do so?

I'm not sure, my expectation would be because oauth is more secure and feature rich than either imap or pop. Jmap I'm less familiar with.

IMAP can be awkward with sync, pagination and has never played great with labels vs folders. JMAP looks promising.
