Is it time to rethink the whole "not your keys not your crypto" mentality?

Here's why I ask this. In the past when crypto was relatively new and you had small exchanges/companies handling stuff, yes if you kept your crypto on their platform and they went belly up or did a rug pull, you were stuck. Made total sense.

However today we have huge companies getting involved like Robinhood and I just saw Etrade is now offering crypto trading via Zero Hash. I get it, the same thing could happen on these platforms and if you don't own your keys, you're still stuck. But then I start to think about it in relation to owning stocks on these platforms. It's not like we own paper stock certificates that we can rely on if an exchange goes belly up. We are at the mercy of the SEC or FINRA or courts in that case.

So sure, owning your keys is still the best bet but is it so bad to invest in crypto on these platforms where we don't own our keys since we've been doing basically the same thing with stocks forever?
