It's not about greedy developers, it's about inexperienced investors. An experienced investor will never invest in a little-known project, even if it seems very promising. Moreover, if investments related to cryptocurrencies need to be much more vigilant. Now really DEFI is very popular and developers are trying to get the most out of this sector. Everyone wants some money. Both investors and developers.
You are right, it's why I don't like the freedom that crypto gives, it's a free crime state out here, we can't expect all new crypto investors to be fully experienced without using crypto before or having any experience about how to know which project is good or bad, newbies is why I'm worried, they are going to keep falling for scam projects
