In 2004 I was still running a Usenet server. Online games were run by the community too. I spent so much time on MUDs.
It seems like now we are in this cycle where someone builds something shinier and fancier, it briefly becomes the next best thing, and then they find out it can't make money (or just survive) unless it becomes significantly worse, and then the next best thing appears. But because of all the steps back there is little real progress. Lemmy too is, functionally, not that different from Usenet. It has pictures and votes and is generally more modern. But what I see highlighted in contrast to reddit is that it's distributed. Like Usenet. It's not supposed to be a breakthrough but after reddit it feels like one.
It’s not related to Windows or Linux, but as the article notes, Apple devices that use UEFI are not vulnerable (and current ones don’t use it anymore and therefore aren’t vulnerable either), so I guess that’s where the “Windows or Linux” comes from.
