Don't try to dictate to others how they should work, as though you're some kind of oracle on the topic.
I'll decide (together with my employer, when appropriate) what software and tools to use, based on a range of factors. Free-ness may be one of those factors, but it doesn't get to unconditionally veto everything else.
Don't use nonfree tools, or you'll become a sharecropper ripe for abuse, such as the complete and utter "it's our computer now, fucko, even though you paid for it" nonsense demonstrated in TFA.
Free software can't behave like this because the moment it tries we'll simply patch it out.

Wow, I had no idea this existed. Thanks for mentioning it. I block the telemetry with settings and with Little Snitch, but this is what I needed from the beginning.
