I think some of the negativity towards the PS3 was due to Digital Foundry doing comparisons of every third party title with the 360 version usually winning out through very minor differences in graphics and performance. This fanned the flame of the tribalist war between Sony and Microsoft fanboys. Very similar to how PC gamers like to shit on console games because of little differences in resolution, fps, etc.
Ironically, the PS3 was a far more powerful console, but this made it harder for developers to work with as the hardware was apparently rather complicated.
It was pure console warring, nothing less. People literally wanted "arrogant Sony" to fail out of spite. The first year of the PS3 was comparable to most other console launches yet it was slandered with the "no games" reputation for several years.
