Re: why the hate?
The problem is that Sony, as with most large corps, can be viewed as a mixture of Good Sony & Bad Sony.
Good Sony is, say, the Playstation - revolutionising console gaming at a time when the established players were either being arrogant bellends (Hello Nintendo!) or driving themselves into bankruptcy with about ten times as many hardware platforms in development as they could actually sell (Hi there, Sega!). Or the PS2. Or the Walkman. Or the Minidisc. Or Sony-Ericsson (early in its lifespan). Or even arguably the Betamax standard.
Bad Sony is Sony Music being involved enough in price-fixing that they were part of a settlement. Or the infamous rootkit debacle. Or pushing the Blu-Ray standard over HD-DVD (with the ugly prospect of problematic DRM rearing its head more and more). Or the excessive diversification of their mobile phone line (consider: they had 98 mobile phones either on sale or in support phase *after* completing an extensive overhaul and reduction of the line overall). Or the various forms of after-the-fact bellendery with the PS3 (removing OtherOS support with a firmware upgrade, going back on their stated intention to provide support via emulation for PS2 games). Or spending several years insisting that everything about the Wii was a big bag o' shite, only to eventually come up with the Move...which was basically a Wiimote with a glowing ball on the end. And of course the by-now-infamous PSN outage/hack.
For the last couple of years, Bad Sony has been in the ascendant, and I think that's what has hit them hard.
