Update: For those of you who want to support Lemmy development without financing the hosting of lemmy.ml, know that the hosting is paid exclusively through OpenCollective. You can see the payment details at this link. This means donations through all other platforms (Liberapay, Ko-fi, Patreon, Crypto) are exclusively for Lemmy development, and not a single cent goes to lemmy.ml hosting.
Edit: Liberapay is the preferable donation option, as it has very low fees and is also open source.
You can still donate to Lemmy without supporting ML! From https://threadiverse.link/lemmy.ml/post/29579005:
