I'm pretty sure they show it something like once a year, and it takes two seconds to close it, if you can't spare two seconds of your life every year for something you get for free then you were never going to donate anything.

I think it's more disrespectful to judge so harshly a company - that puts out wonderful, free, open source software - asking for donations 1 or 2 times a year with a message that is easy to close.
