After you do that here are some IDEs that (so far as I know) don't have data-sharing agreements with third parties.
If you're saying that it's sufficiently vague as to not actually limit them in any way, then I'm wondering what a better privacy policy would look like. One that gives them proper leeway for the legitimate day-to-day workings of a company, but which manages to not be just as vague.
One thing worth remembering here is that the alternatives you mention are exclusively IDEs, whereas the JetBrains privacy policy covers the data sharing they do for their whole ecosystem of products and services, not just their IDEs.
Nice FUD ;)
For the record I dislike both vendors' products equally as much :)

The only comment I posted on this entire post was the one[0] where I said: "Which also seems to be covered by the same privacy policy". I purposefully used the word "seems" because I'm not entirely sure whether that's true, and also included a link so people can check it out for themselves.
If you honestly consider this grifting and intentional misdirection, then I'd be interested to hear what you believe I'm trying to achieve here.
