Could be. But considering spikes after API elimination from Reddit I bet it's a hugely mobile crowd. I myself am a nearly exclusive mobile user. Desktop lemmy is a pretty dismal experience at present I'm sorry to say.
I am too, but moreso because my phone is always there and takes zero time to set up. My computer needs a place to rest, and I can't pull it out while I'm waiting on a train or in line at a counter. I prefer the desktop experience, but 90% of my lemmy usage is mobile. When the computer comes out, it's usually for work.
Do you have a smart phone? A credit card? The privacy battle was lost a long time ago. Doesn't mean we shouldn't fight the good fight of course but it also means that most of us have to compromise to get through life. Yeah, I use Windows cause I won't give up my multiplayer games with anti-cheat that straight up don't work on Linux. Does that mean I should just throw in the towel and use Chrome too? Nah I'll use Firefox cause at least that's something.
