Can't say what you've posted is just. But I can say the if you have a Battlelog account and see the atrocious levels of troll and posts designed for outright abuse retort you may take a different view on the whole thing.
That doesn't justify the combining of forum and game account, but it's only a few 'controversial' examples and is honestly so few and far between that to judge an entire viewpoint on a couple of 'sensationalised' examples such as the reports you posted do ie: they have certainly used them as sensationalist examples.....then you may as well start subscribing to the sun. It's really no different.
But it's EA so automatically fair game to disproportionately slag off.

If you're a jump on the hate wagon or love wagon in polar opposite numpty.
In other words.....
Don't let the nay saying put you off a good MP experience.
It's fair game to doubt Origin; it's fair game to believe it's wrong to combine an integrated game account owth a forum account; but it's also fair game to take the stance that these are few and far between examples and that the links provided have their own grievances

Still wrong at a fundamental level to link the two though. But MEH!
