Well, I don't. I use almost exclusively FOSS software that has no telemetry whatsoever, and where there is any phoning home, I either turn it off or make sure I know what it's doing and am happy with it.

I think it should be the standard, but fact is most computer users are entertainment consumers and their computing devices are just a new and improved TV. It doesn't even occur to them to ask what's going on, hence the ubiquity of proprietary spyware. With TUIs and other nerdy stuff like that, the userbase is generally going to give a shit more, hence the higher standard.
