I don't think it's a matter of preference.

Of course I prefer doing all of my computing on my desktop computer. But I don't take my desktop computer with me to the grocery store. And I use Twitter to entertain myself when I'm waiting in line at the grocery store, for example. When I am at my desktop computer, I'm much less likely to be interested in using Twitter.

That said, one of many reasons I didn't bother creating a Threads account is precisely that reason: no desktop client. Unless forced, I won't use anything that is exclusively available on mobile devices.

I have mod rights on a general subreddit (a city), and I see that mobile is consistently 75-80% of the traffic. That seems consistent with the numbers above.

Most people don't take their laptop to the bathroom.

I think that’s a bit of a tech bubble. My non-tech family and friends all do the vast majority of their computing on mobile.

A lot of people just don't own a desktop, or laptop.

It doesn't really matter whether you know them or not. They objectively make up the majority of internet users.
