Only Reddit neoliberal crybabies whine about "tankies". From what I can see it's mostly baseless accusations/smear campaign because as I said, they are crybabies who cannot deal with the real world. It's an open source project. His views are not relevant to the discussion and not particularly that uncommon outside of isolated Westerner bubbles. Spez the Reddit CEO was the moderator of a paedophile subreddit (jailbait) but nobody is up in arms about that or concerned about going back if the API changes are rolled back. Those people are as lost as old people who love FoxNews, Facebook or any other commercially charged propaganda vehicle.
These leftists you hate so much have done something good. They've seized the means of communication for you. It's open source and decentralised, it's up to you (the community) what to do with it. If you are hardstuck on this then I feel bad for you son, I got 99 problems but the dev ain't one.
It's only a problem if you allow your personal worldview to affect your moderation.. a tendency that sadly most moderators have. I've found lemmy.ml to be one of the more permissive instances where viewpoints of all sides are permitted. Unfortunately many others (you know who you are) are in danger of becoming walled gardens and echo chambers.
