It's not a big enough of a change for people to actually choose Linux distributions over it - those who know about the variable will set it themselves, those who don't will be stuck with a bad default.
My issue isn't with the point of control - it's with the default. Telemetry of all kinds should be opt-in. People shouldn't have to worry that they're constantly being watched. They shouldn't have to hope that every single telemetry stream is operated by competent and careful software engineers, guided by honest and law-abiding managers. You know how this industry works; it's a rare case where a data collection scheme doesn't overreach, accidentally ingest too much, leak data, or turn malicious and pass it to bad actors.
