I dislike that a lot of the games are tied to needing to have the steam client open, also the steam client is a non-controllable aspect on my computer that I own. I can modify (with extensions and browsers) any experience I have online...except steam. I also don't like "leasing" games as that's all they do.

Last note is just I dislike putting any faith into a company to "do good" or to remain with their status quo. Companies are not "good", they are a service provider and shouldn't be anthropomorphized as such for being "good guys" or a company that "Cares"^tm^. The very fact that people are defending it by being sticklers of true definitions of a "monopoly" but hand-wave away the affects it has on the industry makes me concerned it will only become a bigger problem later on.
