Sign me up. I've been unable to give a shit for quite some time. I wish I could give a shit, but the world has become a pretty ugly place, in large part because of deliberate attempts to demoralize those who give a shit.
You see it all over the place on social media. People do a weak-ass form of shit-giving in the form of "raising awareness", the least conceivable level of effort for something you wish you could give a shit about, but don't actually give a shit.
Of course even if somebody tried to GaSaaS, the space would promptly fill with people giving as few shits as possible for as much money as possible. Too many major charities do that: they'll take your money and spend it mostly on advertising for other people to give their money, too, and very little on the things you'd expect if they actually gave a shit.
I know TFA is more about the business sense of giving a shit, but I'd love to see somebody able to give a shit in a larger sense. Unfortunately, I can't give a shit because it seems nobody gives a shit any more -- except the people who are passionately devoted to making sure other people feel miserable instead.
