I'm disappointed. Jetbrains is my daily IDE, and I don't really want to switch to something else at the moment, but this is such a huge red flag it is probably time to start looking.
I just cancelled my subscription and I'm downgrading. The only Ultimate feature I used was the database explorer which is replaceable.
Apart from anything else, this stuff just wastes my time and energy - I don't want to even have to think about the security implications - is my IDE - the main tool for my job spying on me? Is my project which I've spent many thousands developing being leaked somewhere?
Valuable code is battle tested and hardened over many iterations using human intelligence and discussion. It does not come from a LLM.
