I think a lot of people don't have a problem with commercial software, but rather with the disingenuous behavior that some companies display.

VSCode was/is often touted as open source and Microsoft are using it to present themselves as community loving until MS sees an opportunity to extract some money/hinder the competition.

In comparison, Jetbrains is transparent with their offerings and what you get. There is in my opinion a clear difference in how they operate and how they are perceived.
