Like, no matter what, telemetry is useful to the product, and defaults matter. Like the infamous “the opt-ot organ donor vs opt-in countries have a staggering difference of 90% difference”. Should firefox throw away 90% of its userbase’s useful telemetry, most of who would have no problem with providing it?
I want firefox to be good. I don't even need to have the newest features I just wamt a stable browser I can use. Don't we all? Removing features I actually use and adding things I don't need is counterproductive and I don't know which part of their telemetry helped them make those choices, but many I didn't like.

Telemetry should always be opt-in. Firefox throws enough messages your way if they would ask (like many other programs) "Help make firefox better" and then offer different level of reporting it would be fine. They ask me to change my theme at the start, but they don't ask me if I want to send them my data?
Well, this is exactly the point. If you disable telemetry, how do you expect them to know that you are using that feature and they shouldn't remove it?
Turning off telemetry by default is also not an option, because then they would have no data, and would just be making decisions at random -- I really doubt that would please you either.
And now because Mozilla lacks data from its most coveted “tech” users, it does make decisions based on data that it has, which is usually totally opposite (like in your example) which in turns pisses off these users even more and they jump ship, taking all their friends and family with them (because they are the “tech” person in their circle). That is how you lose users.
You can of course make a zero telemetry browser, relying 100% on your own research and what the users volunteer to tell you directly. And those most passionate about it with tell you the most, a wonderful positive feedback loop. But this would require a change of product development mindset to a completely user centric one.
