I'm not suggesting that Google is evil. What I am saying is, these products don't work for me and the reason they don't work is that they aren't interoperable with my own desktop software, or the rest of the Internet. I actually do use desktop calendaring software which will stop working this summer. I communicate with people via XMPP who are not on Talk. I used to use Listen and Reader. I'm only looking to migrate off Voice because it's not going to be available. I was pretty perturbed when all of a sudden, anyone I ever emailed appeared as a pre-approved contact on Talk.
So, it isn't about Google being evil or not. Google has a responsibility to its shareholders to make money, and I trust that they're trying to fulfill that mandate as well as possible. In doing so, they've shifted their portfolio of properties into a closed ecosystem that does not appeal to me as a consumer.
At this point, I imagine most alternatives suck because there's really no point in going up against free and awesome. Case in point: Reader. Reader really was awesome, and it had no competitors because no one would bother competing with it.
I imagine that as Google does offend more of its users, some competition might heat up, but I'm well aware that for most people, none of this matters in the slightest. It's a narrow cross section of geeks who notice or understand any of this.
