I would be glad to take an opportunity to insult facebook again, but actually I don't like this sentiment at all. It just happens so that facebook is among the least trustworthy companies at the time, but I wouldn't be more at ease if they had a good public image and its head would be a baby-kissing politician making donations left and right. Image is just that, an image, and if somebody manages to seem "good" for the public, it only makes them more dangerous and is more of the reason to be worried about them.
Perhaps the only good thing about facebook is the public distrust of it right now. I hated it much worse when people unironically called Google "the good company".
I wouldn't say so. Doesn't matter who, if there is one controlling entity that acts as a business/corporation, it doesn't matter which one. They are all corruptible.
