You may run such a server (I do too... ) but nowadays it is a blip in the data compared to routers, switches, music boxes, GPS systems, laptops, desktops, workstations that run Linux. In those cases, worrying about data from some other user is less likely.

Also I think it was the editor not Linus who said that.

I was going to say the opposite. I think you're making a statement about the number of Linux kernel images running, but I don't think that's a useful measure of prevalence as it relates to the cost of assuming a system is single-user.

On the contrary, I believe the great majority of Linux is multiuser servers and the personal computers and appliances you mention are a blip. I'm looking at the amount of filesystem access that happens.

When I say "multiuser" I'm considering a user to be a person, not a uid.

Incidentally, routers and switches (from your list) are multiuser systems. Consequently, there is a security issue in sending data to the wrong user.
