Meaning you could be the janitor and still qualify AFAIK. Now they are just creeping back up and up againĮducational prices used to be available to not only students but also (reads: specially) to staff and faculty. It's funny, I can remember Nick Martin standing up in the front of the entire company when they slashed the price by 70% or something ($12K down to $3K?) and said "We are burning our bridges, there is no way we can go back to high priced software".
They do everything they can to lock you into a subscription. Also, without paying subscription you don't get access to libraries now, but I could be wrong about that? Also, if you start subscription and then stop, and then want to take it up again in order to get some new release you like, you have to pay a big penalty, or the full amount again. Altium coped a lot of flack at one point for not releasing anything in the year people paid subscription, so their money was wasted. Or you pay an additional few $K each year for a "subscription" that keeps you updated with whatever they release in that time. You have to pay the $9K at first, and then either chose to pay nothing more and never get any update (even bug fixes last I checked), that's called a "perpetual license".
