I'm assuming people are a lot more likely to respond here if they are active Linux users. AKA I think you are probably largely right on the loud minority idea. Lemmy definitely does attract a lot more of that kind of users in the first place.

In my case our house is very mixed. My daily use desktop is RakuOS Linux. My wife is on windows and the only laptop bought as new hardware instead of recycled business gear.

We have a windows server. Mostly because what it needs to do hasn't changed since I set it up years ago. Nearly 10 years ago now. Second set of hardware and technically a reinstall but thanks to domain migration no change of any significance in that time.

Then for secondary computers for myself and all the kid ones it is a sprinkling on windows and Bazzite or Kubuntu. Best part here is my oldest kid (girl) actually has two laptops (low power but lightweight and higher power heavy) and has found she likes the one with Kubuntu better than the windows one.

All phones are Pixel series and use f-droid. That is as non standard as we get there right now.

And zero smart TVs or streaming sticks. I lothe the things. We have one dedicated HTPC (Bazzite) and the others and just near enough to existing PCs to just switch which screen something is on to watch it.
