Opt in is the same as not doing it at all. TFA explains their approach decently well and it seems sane to me.
It's not like this is telemetry in some open source thing for nefarious reasons. It's literally for their customers. They already know who you are, it's not like they're using this for targeted ads.

Prove it. Right, you can't, because once telemetry runs you have no insight or control over what happens with the data. And trust is definitely not an option anymore after all that happened over the years.
