“Lemmy” isn’t one thing. Every community on every instance is different so you didn’t get censored on “Lemmy” you get moderated in a specific community. Lemmy itself (the software) is censorship proof meaning you are free to launch you own instance, as you have done, with your own communities and post there and no one would be able to censor you and it would federate to any linked instance to your subscribers.
I use it to re-tone and clarify corporate communications that I have to send out on a regular basis to my clients and internally. It has helped a lot with the amount of time I used to spend copy editing my own work. I have saved myself lots of hours doing something I don’t really like (copy-editing) and more time doing the stuff I do (engineering) because of it.
