The community edition of intellij and pycharm is Apache 2.0 licensed and you can use those for commercial development. Pycharm is about similar to vs code (I've used both). But intellij blows the Java & Kotlin support in vs code out of the water. It's not even remotely close. Reason, Java has several decent OSS IDEs as an alternative and those would win by default if the only option was a paid IDE. Clion and Rustover are somewhere in between I suspect. VS Code plugins vary from language to language. And commercial non OSS tools for native development are pretty common (e.g. Visual Studio, XCode, etc.). So, I guess Jetbrains feels more comfortable charging for Clion and Rustover for commercial development because they know they are that good. But nothing wrong if you don't appreciate what is on offer. Yes these tools use some memory and CPU. But then I use a decent laptop as well so it doesn't matter to me. Pretty normal to be spending on proper tools if you do this stuff professionally.
