I'm not demanding anything, please stop reading my comments in the most uncharitable way you possibly can.
I'm not sure what has you in super-defense mode, but just as they are allowed to misrepresent themselves on their website, I'm allowed to think that it's shitty to do so. However, as I've said already (a few times, actually), they are more than free to continue doing so (and I'm more than free to keep saying it's shitty).
The point is they're not misrepresenting anything, you just don't seem to understand open source. Literally all of them have the same disclaimer, and obviously they're not going to make any guarantees to randos who haven't even paid them. If this is a problem for you, stop using open source. For a start, say byebye to linux.
As for why I'm "on the defensive", bashing open source projects is bad form. You're absolutely welcome to request a refund, though.

>[...] because they all do that.
No, they don't all do that.
