Established tech companies and their employees have a lot to lose if web3 and related tech would actually become successful.
P2P payment systems and P2P collateralized loans are already there more or less working with a clear path to scaling. If they gain adoption they directly obsolete existing fintech companies.
I'm not saying there's much concrete stuff there yet, but web3 has a clear MAGMA hostile discourse, so it's natural that reactionary feelings arise when web3 gets hype (deserved or not, that's not the point).
Even for fintech there's a lot of value in providing a streamlined user experienced on top of crypto so there's still room for intermediaries. See how many people primarily use CEXs.

I really don't see it. There's nothing in web3 that threatens any of these companies.
See Facebook trying to make a cryptocurrency and then abandoning their plans.
