This is not a useful distinction: most cryptocurrencies and "DeFi" startups seem to be propped up by shady, unattested corporate entities.
If you have enough shady people involved in a particular activity, then that activity is effectively shady. Similar to the fact that if you add enough raw sewage to the water supply, you don't have a water supply any more, you just have more sewage.
Lots of shady people were involved in web startups in 1999 (and still are tbh).
And the only thing keeping these creeps in check is our legal system. Once you remove that, the bottom falls out on quality.
