Simple in the Enterprise

I started playing around with Linear recently (coming from a Jira shop) and it is so simple, and yet elegant (the whole "opinionated software" principle). I love seeing simple designs like this. But why does it feel like these are really implemented to solve basic problems? Why don't we see excellent engineers and designers who understand how to create much more simple solutions work in the enterprise space and try to fix all of the bad apps out there?
