Suggesting that the entirety of the performance difference between Windows and WSL is due to telemetry is by far the weirdest MICROS~1 apologia I've come across.
Performance on my bare metal Linux machines is even better. Do you consider this to be sufficient proof that WSL has telemetry hooked into it?
No, since Windows is less efficient in general.

There have been others who observed the same in the past (and with WSL1), although I do not have a list. I recall reading libc telemetry hooks on Windows that are absent as being claimed to be the cause, but I cannot find the page where I read that. The Reddit post has the alternative suggestion that process creation speed is the cause.
