They regularly put up a banner on the top of every lemmy instance that doesn't manually remove it (I havent seen an instance that does) begging for funding for Lemmy development which is done by people like Dessalines, owner and operator of ML, known advocate for the Russian invasion and person who claims Trans people are just a liberal psyop, and Trump supporter.

If you want a list of citations it's one of the pinned posts on !meanwhileongrad@sh.itjust.works titled "Documentation of Lemmy.ml's Extremism [Megathread]"

Furthermore, even using it at all promotes its funding by the ill informed.
