I think this is bad for Lemmy as a whole, as a community but only due to misunderstanding and generalizations... People are going to equate the "censorship" on the server lemmy.ml as censorship on Lemmy, the platform/software. That is just NOT THE CASE. Please, whenever someone mentions lemmy.ml and its censorship or the likes, be fast to mention that that is a specific lemmy server and the beauty of lemmy is its decentralization and the fact that it is open source. There are plenty of other servers.
I fear that this kind of thing drives people away from Lemmy, when it should not.
Yes, it might sound worrisome, but I dont think you are pushing authoritarian ideology by using Lemmy. The code itself is fine. The code is not authoritarian. The server which hosts your account is also not authoritarian.
Lemmy is, right now, the best alternative for a reddit-like platform. It is something created for the users, by the users. By using lemmy, you are not enriching the wallets of the shareholders. By using something like reddit, you provide content and a select few get to buy a new yacht.
Also, plenty of people are contributing code to lemmy. It is no longer just these 2. The code is also Open-Source. Anyone can fork it and create a new version of lemmy, with compatibility with the current version of lemmy. By using lemmy, you are allowing the possibility that, at any time in the future, someone else comes and says "I have some ideas to improve lemmy, let's do this on my own terms", forks it and continues the work without massively spliting the community.
