I can't in good conscience ignore what I know because there are other things I don't.
If I murder a drug dealer, steal his briefcase stuffed with 100-dollar bills, and eventually donate some of that money to you in USD, you will happily accept it "in good faith". But if I work hard as a nurse, exchange some of my hard-earned savings into Ether, and donate it to you, you will refuse because "there is no uncertainty about where they come from"? I'm confused. How are you certain that the USD donations are clean money, and certain that the Ether must be dirty money? I guess just the vague association with "crypto" is enough?
Just admit that this is about ideological purity and nothing else.
„Even Wikipedia/Wikipedia, a charity with high ethical standards accepts it, how bad can it be?“ might not be the most well-reasoned conclusion, some people will come to it.
If it doesn‘t disproportionately endanger the „core purpose“ of Wikimedia, why not avoid something like that altogether?
Yes, if you don't tell me you did the murdering I would accept the money. Your actions are on your conscience.

I have moral responsibility for my actions. Due to the way a blockchain works, I can't accept or withdraw your Ethereum donation without contributing to the blockchain with a transaction fee. I can't fault you for putting it there, that is a matter for your conscience, but I can fault myself for accepting it.

It is not about ideology at all, but about conscience. I believe ideology is almost as harmful to humanity as the blockchain.
Are you hypothesizing that the net amount of transaction fees paid on the Ethereum network will be higher if you accept the donation, compared to if you don't accept the donation? I have a feeling that you might be accidentally comparing to a scenario where the donator does not donate and subsequently never transfers that cryptocurrency anywhere ever. This is not a realistic scenario. The donator is almost certainly going to transfer that crypto somewhere anyway, so it doesn't appear to me like your action of refusing the donation reduces the net amount of transaction fees.
