That ( https://www.wireguard.com/donations/ -- repeating for completeness and exposure) is surely much better link for donations, as some of us would feel limited with a single "Patreon" option.

There are other possibilities for individuals:

"Monthly: GitHub Sponsors, Paypal, Patreon, Liberapay"

"Once: Stripe, Bitcoin, Paypal"

And also "for non-profit foundations and companies."

Thanks!
