@chinny22,

MMO's usually are either subscription-based or free, and those are completely irrelevant to the topic.
The ones you buy as one-time-purchase from store, must have at least expiration date on them. But they could also share their testing server, that probably has a map of single area with bunch of debugging items around. Let the community take it over, if they want. (And if there is no such "test server", i would question the developers team's expertise.)

VW doesn't restrict you to build/3d print your own pieces to your 74 beetle. Imagine that your 74 beetle required you to connect landline phone cable to it once per month or i wont start. And then VW closed that phone nr., and didn't remove the once-per-month check from your 74 beetle, and denies community to restore the phone nr service on their own.
Publishers actively make it harder for community to take over the support.

I don't think you've understood at all what this initiative is about.

Already singed it when the initiative launched. This mostly just forces publishers to be honest about the lifespan of the product they sell. If being honest about your product affects your bottom line, then maybe you should not be in business to begin with.
