People need to understand that large scale software not having telemetry borders on malpractice if it interacts with the internet. If your software is crashing on a large scale - or worse, causing problems for other people's servers or taking out users' computers - you need to know, and you need to fix it fast. You can't just wait days or weeks to get enough complaints about it from people savvy enough to file bug reports.
Look no further than how a recent Chrome update almost completely broke the software for Citrix users. Their telemetry (somehow) was not tracking this so it took days to get a fix because IT/ops people had to figure out that a Chrome update caused the bug and then escalate through chromium bug reports. Now imagine that happening any time a crash or major bug makes it into connected software...
For stuff that just runs offline, like Excel or whatever, it's super justified to not want telemetry in it if that's the tradeoff users want.
Incidentally this is basically the reason why all the major browsers are on rapid forced (unless you're in the enterprise) updates - the risk of having users stay on older versions with security holes is just too high because it ends up leading to massive botnets. I hate it, but hundreds of millions of people use those apps.
