I'm all for dissing on Ubi and everything, but with all respect to you, I think you're kind of missing the point. Buying stock will do nothing but help Ubi to continue to do what they're doing now. It's not like you're going to be able to buy a massive chunk of the company so that they'll actually listen to you or anything (unless you and some others on this forum are multi-millionaires or something and plan to purchase a controlling stake in the company, in which case you will be Ubisoft and the rest of us get to hate you instead).
Public companies exist, ultimately, to maximise returns to their shareholders. It's pretty clear to everyone except those deluding themselves, these days, that PC-gaming is not the revenue-raiser than the console-gaming market is. We just need to write-off Ubi forever, as far as PC-gaming is concerned, and start hoping other publishers will develop some tactical PC-centric shooters, like back in the good old days where it all began...
I'm not trying to bag anyone here, just pointing out that unfortunately, your idea isn't going to get us anywhere. Don't give Ubisoft any more of your hard-earned money than you already have!
