Digital product companies are always in a bind because people expect it to be free or dirt cheap. They think just because it's bits and bytes it should be super cheap while ignoring all the back end dev costs, support and head office overhead. Unity has like 7000 employees. Most people don't even know the company has lost tons of money lately.
Also for sake of critical mass they often seem to need to price it cheap for usage. On the other hand a commercial erp like SAP isn't going to giving it away pennies on the dollar. The customers are big. A unity dev team might be two guys in a basement. So they got to price it low like a bargain dollar shop. SAP will set a profitable price from the get go everyone can live with. And so can a company selling blenders or bottles of mouthwash. Aside from inflation price increases, most products dont have giant changes like a unity paymdnt plan.
On the other hand a $5 Starbucks coffee is literally 50 cents of ingredients including the cup, they make tons of profit and if a coffee goes to $6 nobody cares. Oh well, that's just inflation!
