You're being down-voted because it's a low-effort comment which comes with a large burden of proof that you've not included. Specifically:

> mozilla is basically a google subsidiary

"Everyone" knows that Mozilla has a heavy financial reliance on Google. So are you bringing this up to suggest that Mozilla also consistently acts to benefit Google and its ad network? If so, where's the proof? If not, what's the point you're making?

> firefox telemetry is almost comparable to chrome

Comparable to Chrome what? Telemetry? Something else? What is Firefox using that data for? In the service of or against users? What's the point you're trying to make? If you're making assertions, where's the proof?

You're making a lot of imprecise comments, most of interpretations of which carry a large burden of proof, and then complaining that people are just down-voting and moving on.
