By all means donate to GnuPG, but do so directly instead of encouraging bad practice (such as letting someone else generate the key for you). If you are just playing around and generate a vanity/compromised key then verifying the key id is not useful, hence you don't need it to be easy to remember, which negates the reason for generating a vanity key in the first place.

I'd rather donate 100% to GnuPG and not get an insecure vanity key.

No I shall not, donated 100% directly to gnupg
