I agree this may put off some devs from making types, but the alternative right now is poor consumer experience. Its a trade off but one I think is better in the long run.

Or what I would hope for online games is that the license consumers buy would clearly define a minimum length of availability for the online side of things.

By making these plans earlier it may influence the architectural decisions the studios choose, reducing the eng effort to make games better supported at end of life.

From my understanding of the initiative it won't force developers to support games indefinitely but will get them to document end of life plans early (even if the plans are the game will no longer run) so as a consumer I can make a better decision.
