I bought Affinity Photo and Affinity Designer in May of this year, less than 6 months ago. Some companies that offer perpetual licenses would simply give me the upgrade to the next version for free since it came out within a year, and basically all of them would offer an upgrade discount that isn't simply a launch sale, into perpetuity.
The price is good for decent software but it's kind of discouraging me from wanting to upgrade, when their goal should be the exact opposite of that.
I'm an existing customer, and I look at it as 40% off for existing customers to upgrade, and also 40% off for people upgrading from Adobe.
