It used to be that vendors could tie their cost to the value they provide, but now their cost is more correlated to the token spend to reverse engineer and re-implement them (using appropriate clean room controls etc). If their cost goes to far above the AI-driven re-write, they're more likely to get jettisoned (absent some other moat not included purely in the technology).
I'm sure we can all think of products that charge a fair whack in license fees, but would not be massively difficult to re-implement (or at least for the subset of features actually used).
