Physical Comparisons
Another way to think about this is to consider how the same legal framework being considered here supports other types of goods and services.
For example, many of the most beloved and classic "analogue" cars continue to be supported by third parties and enthusiasts many years after production is stopped by manufacturers. Anything from E-Type Jaguars to Morris Minors live on today thanks to that commitment from owners and enthusiasts. So when we see companies stating that a software product they created "is no longer viable" then, as many other technologies have learned, transitioning to a community support doesn't just allow that technology to live on, it can give rise to thriving ecosystems and communities.
In other words, what the Commission seems to be doing here is in fact making a "special case" exception for software. The refusal to act [by the Commission] is in fact creating a new legal framework.
Personally, I would like to see studios that release MMO games set up a "Community Inheritance Pledge", *before* a game is released. In other words, if you're intrigued when Bungie announces "Destiny 3" [or whatever it ends up being called], you can evaluate whether or not to commit funds and time to playing the game based on whether or not the studio makes an up-front pledge to release the back-end server code as an open-source project in the event that they decide to withdraw their own support.
If studios did that, then you would be free to make your own, informed, decision as to whether or not to support the studio by making a purchase. Especially relevant when we read of some players who have spent literally *thousands* of dollars on a game - think the pay-to-play variety, like Star Citizen or Eve Online, where players are given a choice between "endless grind" and handing over more cash...
Curiously, however, I also think that writing a compelling, stand-alone game not only requires more effort [because there is no scope for the community experience to augment anything the game lacks] but I think it can produce better games.
Caveat emptor, I guess...
