Probably because the people in question are still drinking the Kool Aid.

Sounds about right. I've only met a handful of devs in crypto. They were all in college or recently graduated individuals. I don't know if they were getting paid in cash or tokens, but it was hinted at that they were being paid, at least in part, under the table.

Most of the crypto workers I've met in the last six months have been mostly freshly minted MBAs or marketing people with tons of money to burn.

There's nothing wrong with developing cryptography software.

More about intentionally breaking it.
