Apple forbids us from having a simple link to wireguard.com/donations/
in the version info window, citing the existence of this link as a form
of payment outside of their in-app purchase framework that requires 30%.
The link had been there for around two years. After rejecting an app
update for a critical networking regression unrelated to this, they
wrote:

From Apple
3.1.1 - Business - Payments - In-App Purchase
We noticed that your app allows users to contribute donations to the
development of your app with a mechanism other than the in-app
purchase API, which is not appropriate for the App Store.
Next Steps
To resolve this issue, please revise your app to use the in-app
purchase API to pay for this type of transaction. Please note that
even though tipping another individual is optional, the tip is
connected to or associated with the receipt of digital content or
services in your app and must be purchased through in-app purchase
in accordance with guideline 3.1.1 of the App Store Review
Guidelines.
Please see attached screenshot for details.
Trying to appeal this or reason with Apple is not going to be a fruitful
endeavor, so instead we simply cut our losses and remove the donation
link entirely. The goal, anyway, is to get a timely critical update into
the hands of users, and encouraging Apple to block that further would be
a disservice.
