If libsodium is useful to you, please keep in mind that it is maintained by one person, for free, in time I could spend with my family or on other projects. The best way to help the project would be to consider sponsoring it, which helps me dedicate more time to improving it and making it great for everyone, for many more years to come.

You are absolutely correct. However, that's the mechanism that Frank has made available, and that's what the comment I was replying to was asking, so I was just connecting the dots between the question and answer.
