So jetbrains allows everyone to use their marketplace and their plugins outside their ides?

I can download the jetbrains php extension add it to my own shell and not pay for it?

they never gave us the impression that they were going to. No rug pulling is the name of the game here.

For both questions, I don't know, probably not. Sorry, I do not understand why you ask this question. Jetbrains' IDEs aren't open source.
