That mod was for the original Crysis (Warhead), and it didn't have enough people for Multiplayer in the first place anyway because most people couldn't run the SP, let alone play with others at that time. Battlefield is simply going downhill since BC2, which was the last true BF in my opinion, with free content patches that added onto the game and a paid DLC which was worth it since it actually changed the game (just compare Vietnam to Hardline - 5 guns, a bunch of new maps and a bit of tweaking on the guns). BF3 can be saved and VU is the way to do it. There's still a huge playerbase on PC and there will be more reasons for it to expand once VU is out. Keep in mind that VU doesn't have a lot of people, not only because there aren't that many keys out there, but also due to the lack of promotion. And as stated in the past, they don't want to promote something that isn't even out yet as things may change over the development course and displease some of the fans who were in it for one thing or the other. Imagine if all the popular BF YouTubers were given codes and let in to try out the features (when they are developed and brought in), similar to how they did with BF4 and Hardline while still in Alpha/Closed Beta. Imagine how they play on night time maps, with custom settings and more server-side events (like turning Levolution on and off in an instant or adding in new props / moving old ones). With enough publicity, any game can gain the playerbase it needs. I don't exactly remember which game it was (think it was a Tony Hawk Pro Skater but don't remember which) that PewDiePie played a while ago and the publishers ordered more copies to be made (for an old game that was no longer in production) since people demanded to play it. When Nofate and Kiwidog decide it's time to let in the hounds, they will. Or if they don't want to promote themselves through YouTubers, there are plenty of other ways (including MordorHQ).
