I think a case could be made that they should.

At some point in the software as a service world (driven by web apps), we started accepting that a manufacturer can break the software we use (change it so it does not have the same features or even just UX we are used to), and is now mandated to provide security maintence but can still do that by simply forcing a customer to their new version.

I understand the economics of this, but this is why I loved LTS releases and their commitment to backport security vulnerabilities.

Hopefully with GenAI, companies sprout that will support this for consumers too!
