Campaigners urge EU to mandate 15 years of OS updates
(www.theregister.com)
This is a most excellent place for technology news and articles.
I think it would need to be a commercial product like Red Hat or preinstalled OS by the company that sell the computer.
With a FOSS distribution that is made freely available without charge, that people download and install themselves, people are probably themselves responsible for their choice of OS.
