VSCode, XCode, VS Community, Android Studio aren't free beer as such, the salaries of the teams come from Apple hardware, Windows and Azure licenses, Google Cloud and 30% app store,...

Thanks for pointing that out, because it was not on the linked page nor on the main page. They do a good job of never mentioning it anywhere on the main pages. (I suspect that's intentional. It's always one extra click hidden--It's buried under the Community tab which then has a Download tab. Or it's under the Try Ada now which then gives you a GNAT Community Download button.)

The lack of transparent pricing is still an issue, though.

Sure, you can also find it packaged on many Linux distros, e.g. https://packages.debian.org/sid/gnat-gps or https://aur.archlinux.org/packages/gnat-gps/

I usually prefer vim: https://github.com/thindil/vim-ada

VSCode: https://marketplace.visualstudio.com/items?itemName=AdaCore....

You can just do `apt install gnat` or `pacman -S gcc-ada` for free :)

I have been using gps for ages, it is free.
