sure in the tech industry we all know the best practices and more or less try to follow them, but in general I've found that I often have hardware that keeps working long past the desire of the corporate overlords to support it:

- a windows 2000 laptop that I only stopped using (a while) after win2k stopped getting security updates, and the linux i put on it didn't work very well.

- a flip phone that was gloriously good at doing the only two things it knew how to do (calls and sms) that I had to stop using because it literally stopped having compatible towers to talk to.

- a 2013 macbook with a keyboard that still works, but it can't get the latest OS updates anymore, much like OP's XP machine.

I feel like there's a willful blindness -- it's very profitable for companies to keep everyone upgrading all the time, but it creates a lot of trash and there's really no need. There's a huge swath of the population who doesn't mind having 20 year old appliances or cars, and who views their digital tools as just another appliance to be replaced as infrequently as possible.

Those of us in tech need to consider the moral prerogative of slowing the trash cycle and the frugality enabled by letting things work for decades. And to stop pretending there isn't a user base out there who will insist on using things for decades even if we tell them it's not advisable.
