You know that any software that requires a login or can update on its own can be bricked at a moment's notice if someone in legal or accounting changes their mind about the whole "perpetual" thing.
There's a dialog within the program to enter your key though I haven't checked if it connects to the internet at that point. I use an account so I can easily use it on several computers.
This is true, but compared to the prevailing alternative I'll take it. Unless there's a viable FOSS alternative for whatever software we're talking about at the time, of course. :P
