They don't care. Their entire mind set is predicated on the idea that every one should be forced to play one way to provide entertainment for them. They genuinely couldn't care less about other people playing a game they spent money on in the way they want to play it.
I work in an industry where I have the 'pleasure' of dealing with people close up every day of my life. A small number of them are nice, most are....not. When I get home from work I do a number of things. I DJ, I make music, I run a music blog, I do a bunch of stuff. I play computer games for 30 minutes of escapism at night. I have NO interest what so ever in meeting people, in chatting to people, in engaging in little ego-bathing contest with people, cooperating with people, fighting with people, asking about the weather with people. I couldn't care less about people. If I was purely scared of playing against other people as the little sheep on this forum keep insisting I could play in a group like Mobius. I don't because I am not interested in playing with other people what so ever. Couldn't give a rats ass about any perceived social aspect. It has never been why I play games.
I. Am. Just. Not. Interested. I bought a game that had three play modes: online, solo and offline. They took one mode away which was very nearly a massive deal breaker for me. Should FD screw me out of the one way I play the game in order to pander to a bunch of mmo trolls. I'll take my money elsewhere - and I'm one of those people who would have probably bought every dlc and expansion.
I've played many online games and mmo over the years and I'm sorry, the idea that the multiplayer aspect and the opportunity to play with other people is anything interesting, exciting or special is one of the the great myths of 21th century gaming.
