Since the only wording is "providing reasonable means to continue functioning of" when someone interprets this as extreme as "MMORPGs must run their servers in the cloud forever in case someone tries to sign on 70 years from now" and someone else interprets this as mildly as "Games with single player modes must be allowed to launch without server connectivity at the time cloud services are retired" it becomes difficult to immediately refocus talk about how "this" does/doesn't should/shouldn't will/won't apply to other software since it's not even a strong agreement on "what" we're really talking about.

That said I'd hazard a bet most people supporting this also support similar feelings about generic software as well. Sometimes it's just easier for regulation to start in one "obvious" case and spread out from there rather than hope to wait for everyone to agree to change everything at once.
