Gods I hope this is just a fluke but reading OP and some comments it seems that it is not. :(

In any case, first thing I always do when I install a printer is to give it one exact static local IP because I made a firewall rule that blocks all outgoing WAN traffic from that IP. I lost faith in all my periphery to not sing behind my back and took things in my own hands.

My Brother MFC works amazingly well and I will not think as a programmer in this case; I'll be a normal human who says "no need to update it if it works" and leave it at that.

So far zero complains and I am happy with my device. And with these news I am even happier that I am paranoid and make sure my device doesn't get a firmware update.
