I have no problem donating to good projects, as I have done in the past. And I have no problem donating to Ubuntu. Lets face it, it's the base for Mint, and even in its own right an amazing OS. But I do worry that perhaps things aren't so rosy over at Canonical, and that's why they need to put this type of thing to the forefront. Could Ubuntu be struggling now, and be in need of serious cash behind the scenes? I hope not, as to me it's massively important in the computer world now, and no one can afford to lose it imho.
