I don't make any moral judgements about it but there are reasons why you would not want to do it. Like, maybe you feel like we need to grow the number of people in crypto, not move them around. Maybe you don't want to start a talent price war with deep pocketed competitors, etc.
In my experience building product teams, diversity (members from different backgrounds) has always made teams stronger.
We don’t want crypto to get to homogeneous. Rather, it’s better to let the tenets that crypto brings to spread and grow to others.
