I'm fine with them since it makes no difference to me if a game I buy for the online multiplayer has also a singleplayer or not. If as example Battlefield has a singlepayer or not doesn't change that i would play only the online multiplayer and that will be much more time as I would ever invest in 95% of singleplayer games so that I get much more playtime with my online games as i do with my singleplayer games even if they shut down the servers after a while.
Sure, it would be great if I could theoretically play an online game even 20 yearsd after release but I don't think that I will ever miss that. I also don't play my old singleplayer games on my old consoles even if I could.
If they make an online only game out of a franchise I love for the singleplayer is something else but that doesn't have anything to do with the servers and more with the fact that I want that game as singleplayer game.
