It seems that way with a lot of REST clients for whatever reason.
It starts off as what we all want - a simple rest client, maybe storing environments and requests
Then companies start building more features to try and create a whole community or ecosystem
They start asking for account creation. Then team creation to share with your team. Then an enterprise plan. Then they gimp the original features and paywall them.
The thing is, I kinda get it in a way. Like, having an account lets them offer so many more useful features, and over time they might just see it as not worth supporting two "types" of users, so they lean more on requiring an account.
Obviously, a lot of this is driven by execs trying to make their line go up, but even without that it does make sense to a point. Not that I agree with it at all, but I see how it would happen.
