The only people "relying" on this are other startups whose VC benefactors force them to use other products under their portfolio in order to goose up their numbers.
I've raised venture from a lot of the big firms (and a lot of small firms) and have never had any of them attempt to force me to use anything.
that makes so much sense. I always wondered how the fuck did all those ZIRP era "hello world as a service" bullshit startups have any customers at all.
