Not the OP, but if you run a business, you must be very careful to correctly declare all your income, make sure you invoice properly, pay taxes, etc.

Just because soneone “donates” money, it doesn’t mean that you don’t have to pay taxes.

So in general it only pays off if it is above a threshold. If a company offers to donate 2000€, I would find a way to make it work. But if it’s just a one off donation of 10€, I’d rather not bother my accountant with it.

Not being in the US, not trusting PayPal and wanting absolutely nothing to do with any kind of blockchain currency.

It's interesting that we have much simpler payment methods available in the EU, but apparently EU people don't like to pay for things.
