+1 for -Rot in hell before I go cloud AND rent software. It's bad enough that my CAD program MUST connect to their license server before use - there's been a couple incidents when
their server was down, and I was up shlt creek without a paddle. When I complained on the forums, I was removed from them :-) .. and now I get NO replies from support emails.
So, if one day they decide to close it down, my canoe is suddenly full of holes ! Dongles are even stoopider.
