IMO it's an overengineered sloppy mess. It adds too many bells and whistles without taking away anything. Nul checking is about the only serious feature it has. The rest is chrome and bling. It's "ricer" Java.
Reading Jetbrains' EULA makes me think it would be an easier read if they just listed the entities they would NOT share your data with.
vscodium[0] might require some aftermarket bells and whistles to reach feature parity with jetbrains' "swiss army kitchen sink" approach but at least vscodium is not data-mining me.
For languages like kotlin, java and even python JB is still way ahead of the competition.
