It's like this. Most of the companies on the list are bad, but have wound up seriously getting theirs. As this article mentions "Bank Of America" has wound up getting slammed in the long run by the people it victimizes, and the US goverment. It's suffered 40 billion in lawsuit settlements for it's behavior. Companies like "Haliburton", British Petroleum, Wal*Mart, and others, have all taken their lumps in return over a period of time.
The thing with EA is that their behavior is so far met with smug invulnerability. EA does all of the garbage that people hate it for, yet it never winds up suffering any penelties for it, it keeps right on doing what it's doing, creating things like EULAs that prevent class action suits to prevent these kinds of responses, while pretty much telling people that they can either deal with their greed and abuse, or go without their video games and IPs.
It's important to note that EA's influance is also felt throughout the world of media, the things it spearheads like Microtransactions, DRM, etc... (even when it doesn't invent them) tend to then get picked up by other media producers. The fact that it's rapidly getting to the point where you can't play a game without being online constantly, and are going to be nickel and dimed even with single player games, largely comes from EA, and other forms of media are apparently looking at their success and finding ways to exploit it.
To put things into perspective, Bank Of America might have done some really bad things, but it only really effected some of their customers who noticed. BP caused oil spills, and they are nasty, and will be a chore to clean up, but don't directly effect most people in the civilized world and will eventually be dealt with. EA on the other hand has brought it's antics into most people's homes and lives, even if indirectly. You can arguably blame EA for your kid who runs up a $5,000 microtransaction bill, because they are the ones who largely made it so everyone and their brother are jumping on that bandwagon.
Honestly I think what we're seeing with EA's election is more of a sign that the goverment really needs to get involved to stop the kind of exploitions EA is involved in, while not currently illegal, or regulated they probably should be. I think people are pissed because EA keeps feeding them crow and nothing happens, because there is no avenue to effectively pursue it unless you want to go without their product. At least with say Bank Of America you can file lawsuits (and win, as you see) and can choose other banks. With EA, if you want want of those IPs you pretty much have to deal with all their DLC/Microtransaction scams, DRM, always online connections, nor do you have any real recourse if they wind up screwing you on a product unless they choose to provide one (see "Simcity" and the problems people have had getting refunds for it). You can't just choose to say buy "Dead Space 3" from someone else that isn't going to put douchy microtransactions into it.
I think a lot of people laughing about this tend to mostly think in terms of how EA is "only" a video game company without bothering to look at it in the big picture and how it pisses people off. Sure in the scope of things their product seems petty, but the invulnerability with which they exploit people is not. Not to mention that IPs, digital property, etc... are becoming a big deal nowadays and the precedents EA is establishing are very bad for the consumer. Practices EA makes normal now could be being used to exploit consumers for centuries down the road, long beyond the time someone finally finishes cleaning up one of those huge BP spills with engineered bacteria ( or whatever method the use, but I've been hearing stuff about how ever-improving petroleum munching bacteria is going to solve this problem in the long term... an idea going back probably decades now, I believe Dean Koontz used such as the weapon that eventually killed the monster in the book version of "Phantasms" as well if I remember... just to end with a bit of pointless nerd trivia).
