I believe the pricing is high by necessity - we're talking about employing some dozen of people on the higher end of competency doing terribly unexciting work. Hobbyists should settle on the Hopper tool, which is $99 a year.
Also, if you wanted to advocate for FOSS, compilers are an all around terrible example. In fact, they prove my point: thanks to GCC and the likes, we're still stuck with hodgepodge of fragile build systems, platform-dependent code and poor IDE integrations. Hell, modern programmers will be right at home with 1988's compilers, seeing how Makefiles are still somehow relevant even today.
Compare that with the early 90's Turbo Pascal which had an IDE with a built-in help system, a build system, a debugger, and a profiler. We could've had competition to improve upon all that, and instead it's 2021, and you have to spend hours per project to keep the tooling from breaking. In my carreer, I've probably spent more paid hours setting up "free" tooling than I paid for commercial tools. It's just a sad lose-lose situation for everyone.
