This is why we need Right to Repair.
Because customers want to keep using the things they've bought after companies want to (or are able to) support them.
Just because the original company doesn't want to support something anymore shouldn't mean it's garbage now. Customers should be free to fix it themselves, and if there's enough people out there who want a fix, it should be possible for a business to be started around providing that fix.
(This does have major implications for how companies should be handling source code, build/dev tools, and documentation... I'd say that when software reaches EOL, it needs to be made open source. Like ID Software has always done.)
