I think a good example in support of your statement is the superfluous metrics wantonly spewed by, eg, Firefox. A cursory perusal of about:config will list many many default settings which are completely unnecessary for normal browser function, eg dom-battery, general telemetry, dubious DNS and dozens (maybe many dozens) of other better examples I've seen but don't immediately remember. The privacy holes here are mostly by design. Clearly more than necessary hardware info.
There are endless examples of data flowing where one wouldn't expect. Doesn't IP6 wrap the MAC address into the IP? This alone is pretty significant. It goes on and on, but I don't see this as an excuse to go full-nudist in a fit of futility with all data.
And another thing I frequently wonder: who benefits? I honestly don't see things functionally improving in a way that I can't live without as a result of all this telemetry. I don't see that many people clamoring for the kinds of improvements this telemetry is supposed to enable. I know technology does improve, but I just can't remember where things were so bad I needed to mass-email my dossier to the world. Generally, I just made a forum post or bug report.
