IMO the main reason why Origin is getting a bad rep from everyone is the exclusivity deal they announced yesterday. Most people who are on their preferred digital distributor like steam would like all or most of their games on steam. Since Origin is trying to get more people to use their service they announced that most new games will be exclusive to Origin for a certain time period. Most people don't like that, like me I would like to get Mass Effect 3 or the next Dragon Age on Steam and play them on day 1. This forces me to either wait for the game to come out on steam after a week or month or get it from Origin.
This is primarily the reason why people are already hating Origin.
I would have liked to get my games off steam, but I'll wait or get it off other sources and play till they release it on steam.
