How many people had rented servers for games? A lot. Now video game companies have turned game servers into a SaaS, whereas then they just released Linux server binaries. In the early 2000s there was a bare metal server rental company on every other street corner.
How many people had Linux/BSD network appliances? Also a lot. There was such a time when all you got from the cable or telco for your broadband service was a modem, and you had to roll your own router/switch. There were a multitude of run-from-a-floppy (or USB stick) BSD and Linux router distros back then.
Also, you're not correct on PHP. The entire reason PHP grew so wildly was because it was server side rendered, and both AOL and Microsoft intentionally hindered their browsers' javascript capabilities in lame attempts to monopolize the internet.
