Companies I hate

SCO & ALT Software & Rogers 

Why I hate them  

If you're a techy, then SCO is self explanitory.  They're on a linux killing rampage (good luck). 

As for ALT softaware, I worked for them.  There are a few nice people there but in general the company is a horrible place to work and I'd advice anyone to stay far far away.

Rogers... I hate most of all.  Cell phone bills from there, cost me more than my car.  They have horrible customer support and they have horrible service.  I think they are by far the worst cell phone company in the world.  I switched to Fido to get away from Rogers, and within a year they acquired Fido.  Now I have to change from Fido.  The service from Fido got horrible upon being acquired by Rogers.

That's it?

There are other companies I don't like, but in general these are the only  ones I devote energy into hating.
