Fair enough though, maybe there's some truth to what you're saying, and maybe there just aren't that many dedicated PC gamers around anymore. That said, among so many potentials, it's a pity you have only one example. Jury's still out, I'd say, which makes me anything but trolling.
There are plenty of PC gamers around but it can't be treated exactly like console platforms. Some genres aren't traditionally well represented on the PC or don't work as well due to control considerations. A lot of publishers seem to just expect that when they put their games on the PC that they should sell X number of copies no matter what. I understand from their perspective they are just looking to recoup costs and hopefully profit but there are other factors than just having your game out there.
In the case of Ubisoft a lot of their catalog simply isn't going to sell millions of copies on the PC, they are going to need to adjust their expectations and be more selective. Turning all of their IP into online properties isn't necessarily a recipe for success though. Speaking as a consumer I don't like the constant delays with their PC releases either, I often find myself skipping their titles because I've largely forgotten them by the time they arrive. I'm also not happy about the constant DRM, I don't want to have to go digging on several forums just to find out how hard they're boning us on that front this time. They aren't consistent with it either, they change it up almost every release and it's becoming tiresome.
I think Ubisoft made a mistake with the I Am Alive announcement, that's exactly the kind of small scale downloadable title you can throw on steam and make a very respectable profit on. Ghost Recon well, it's a shame whats happened with it but I think its older audience has largely given up on it anyway so I can't fault them for trying something new.
