Maybe we differ in how we understand what "SaaS" really is (a debate which is as old as the concept of "SaaS"). For me, if you offer something software-y behind payment, and the software can only be accessed online, it's a SaaS. No need to offer premium pricing, enterprise tiers, support or anything else. Putting up a online API/UI that is locked behind payment, it's a SaaS (in my eyes).
