It's not hypocritical to feel different about different types of telemetry from different companies. JetBrains makes software I like using, and hasn't given me much reason to think they're being nefarious. Microsoft makes software I hate using, constantly betrays user's trust, shoves ads where they don't belong, uses dark patterns to trick people into using their services, ignores user defaults to promote their own shit, repeatedly installs software I didn't ask for, replaces working OS apps with shitty replacements that don't work and crash constantly... need I go on?
Windows exists to sell ads and Microsoft services, and no one can go anywhere because they're locked into legacy software, and Microsoft constantly abuses that position. JetBrains IDEs exist to sell themselves to businesses as a productivity tool. They benefit from making it actually good because no one is locked in and they have real competition.
Not to mention an OS has more access to my data than an IDE. If JetBrains suddenly decided they'd bundle a feature in IntelliJ where they constantly record my entire screen at all times, I'd be much more wary about their telemetry.
