1) Disney likes to withhold paychecks for long periods of time for "accounting snafus"
Disney isn't alone in that though... many animation studios are notorious for not paying their employees until long after production is finished. I have friends who have gone up to a year without being paid for their work on major cartoons - some not being paid at all.
Another reason Disney is evil is because they purchase US rights to Japanese animation, yet fail to promote it (only showing in select theatres) for fear of it overshadowing their own productions. Not that I give a fuck about most anime, but the idea is still irritating.
Everybody I knew at the studio I worked at thought Disney was evil. They would work there in a second given the chance though. Kinda like IT workers and Microsoft. :/
