It's so easy to provide the DLC as a free download and give it to some file hoster or to google or to an internet archive. Obviously they are not interested in making money anymore, so I would actually force them to either support it or make it free. This way the benefit for all is maximized.
Actually that might not benefit EA. They don't want people to play their older games (for free), because then people have less incentive to buy newer games from them.
I believe many game publishers feel it would be better for the business if all games had only a limited playtime after purchase (or even the original release date), e.g. all games older than 2 years would vanish into thin air.
Excluding games where people are ready to pay monthly fee for playing the same game over and over again (WoW, whatever SW MMOPRGs EA is now releasing...), or if they play the older games through services with monthly fees. Then it is the opposite, it makes more sense to them to make long-lasting games and keep investing on them, instead of investing into development of newer games.
Planned obsolescence, you say? I've always thought of DRM as a digital form of planned obsolescence. I don't care what it says in an EULA either. It wasn't presented to me like a contract at the sale, and if it would have been, I could have negotiated it or refused it. I don't care if a company wants to push new products as its business model, but if the only way to do that is to make defective products to try to force people to buy new products, they deserve to fail.
I do believe that people would be willing to spend money for a more durable product. At the power company I used to work at, they would regularly spend another $20,000 per truck for the more durable digger derricks and aerial devices after they had previously bought other trucks that would break down and have to be repaired frequently (even though they were non-profit they still had the discretion to not be forced to take the lowest bid unlike some public services.) It wasn't just the cost of repairs that vexed them, it was the down time.
I remember one time a salesman from a certain truck company dropped off a digger derrick for a week to let us test drive it. He knew we probably wouldn't be buying from him since this company was the main reason why the power company decided to purchase more expensive trucks in the first place. The lineman had been vocal about it at trade shows in the past too. So while the salesman was there, one of the lineman tried it out. Tried out the auger and one of the auger teeth fell off and the cheap plastic handle also came off the lever to run it within a minute. "It looks like we'll be buying from Dueco again." Everybody laughs. Good joke.
You probably don't know the names I threw out (I doubt they ship to Finland) but I thought it was a good example of people willing to pay to get products that are not designed to be defective. I think it works out better in the long run. It builds trust.
