PyCharm and IntelliJ Community don’t have commercial restrictions. I’m still pretty anti-RustRover given this and the whole bait-and-switch where they turned the open source Rust plugin into what is now a closed source, paid editor. JetBrains still had done nothing to ameliorate this.
It wasn’t obvious because I’m not quite sure why someone would suggest using software that both needs regular updates and will never get any more updates because those updates along with good faith open source contributions have been moved behind a paywall.
