Basically every Android and IOS app you use collects telemetry

So it's OK, then. Jimmy jumped off a bridge, so it's OK if Johnny does it, too. No harm done!

but suddenly when Microsoft does it it's a Big Deal

No, it's a big deal because Microsoft feels entitled to collect information about people using... wait for it... a calculator.

using anonymous data

It's not anonymous. We know it's going to at least get a timestamp and IP address.

I don't see the issue with refining UX

Neither do I. Do it by bringing people in and testing the program on them, the way it was done for decades before "telemetry" became one of those SV euphemisms.

Every high quality commercial app does this.

No. They don't.
