I would say Microsoft, whatever they do is not good for gamers or the games industry. Most of their games are considered irrelevant (Kinect, XBLA, Multi, PC or if in this list Halo/Fable/Gears/Forza) and will never "reach" the quality of Sony titles. They get criticised for being irrelevant in Japan (who cares really), some still think RROD is a thing of today and tomorrow. Xbox Live for being a paid service and be "packed" with advertisement.
Both Sony and Nintendo gets a lot of hate too. Sony for their "poor" online. Their games are not selling as much as the competition and are trying too much to "copy" others.
Nintendo for catering to a different audience, for releasing only the same mascot in almost every games they make, for being a generation below the competition and for WiiU's "sub next gen" new offering.
I don't visit Sony and Nintendo threads as much as I visit Microsoft's threads but like one pointed out, people will be more sensible to criticism towards their console of choice.
