Honestly, I think any software business model where you're not paying an explicit monthly/yearly sum is more deceitful for B2B. No business wants to use a software product that is not being actively maintained, so even if you get sold a perpetual license to "own" a version of the product, you will keep going back to the same vendor to get new versions. So, you are actually still paying a periodic fee, just maybe with capex instead of opex. And if the vendor goes out of business, you'll have to start moving to a new product, so you didn't really "own" the software any more than if you had been paying an explicit rent on it. Now, SaaS where you are sending all your data to the company's servers is probably one step too far, for various other reasons. But perpetual licenses are generally a bigger scam than periodic ones for business software.
