Most telemetry is more along the lines of "user spent N minutes on platform, clicked on these things, looked at these other things" etc etc. And the primary way devs use this data is by aggregating across all users and running a/b tests or viewing longer term trends.

Are some companies spying on you the way you say? Yea, probably. Most of us just want data to know what's working and what's not.

The logical conclusion is you’re asking for no local products and everything to run server side. It’s kind of a ridiculous position that doesn’t change the spying being done other than it’s on the other side of a browser.

I agree, but once you cross the borders out to the internet, I'd say you need to stop seeing that as "Me sitting at my computer at home", because you're actually "on someone else's property" at that point essentially. And I say this as someone who care greatly about preserving personal privacy.
