There is an issue of who calls the shots -- if you solicit donations from your users, that's who you are beholden to and need to serve to get money. If you are soliciting third party advertisements, that's who you are beholden to (and if you are using a third-party ad placement service, you are beholden to them as well as, perhaps more than, the actual advertisers.)

That is one issue, indeed. But the downside is that you're hassling your users to give you money, rather than hassling advertisers to give you money.

I'd rather not be hassled as a user.

I would also click on adverts, and buy things if they're useful to me, but I don't think I'd ever donate to a website.
