I might be open to the idea, but it would need to be a trustworthy company that doesn’t cancel stuff left and right. An ide would be too annoying to switch constantly to take this risk.

(What do (you) mean? ( Lisp certainly has its (downsides) and (upsides)))

This seems more focused on commercial license holders. here paying for your ide is not that uncommon, and also the amount of revenue to be gained is a lot higher. That being said I always found it a bit weird that jetbrains didnt make clion free for non commercial use as they did with pycharm/intelij.

Those certainly also look nice, did not notice those

The second part has some of this, but not as in depth as i’d like.

Back in the day before university (around 6 years ago) I got recommended a mooc(massive open online course) by the university of Helsinki. I used this course to get started with learning to program, and to find out whether it was something for me. It has been some time, and it seems they update the course but I hope it can help you too in learning. Here is the link: https://java-programming.mooc.fi/. It really starts from 0, with setting up te environment which is nice. It is in java using the netbeans ide which some would call antique, but in my opinion that does not really matter to start to learn.
