I do, but only to support FOSS users in some communities that are not here [yet]. There is no opnsense community here in Lemmy, so when I see questions there in reddit, I help where I can.
However, my “bio” or whatever it is called in reddit, clearly states that I have moved to Lemmy permanently.
I am actually considering creating a opnsense community here and hoping that Franco will come and join, and take over ownership.
