When you signed that contract, they said you were buying a tool. What you actually got was a permanent, compounding obligation. One that rises every renewal cycle, expands every time you need a new capability, and extracts maximum value from the fact that leaving feels impossible.
The mechanism is always the same: engineer the switching costs high enough that leaving feels impossible, then raise prices annually on customers who can't easily say no.
This is not an accident. The switching costs were engineered in. Vendor-specific scripting languages and proprietary automation runtimes that run only on the vendor's infrastructure. Partner ecosystems of thousands of consulting firms whose revenue depends entirely on your continued subscription. And, increasingly, the policy itself: one mega vendor's April 2026 API policy update prohibits autonomous AI systems from sequencing API calls against their systems - except through their own AI runtime. The lock-in is now contractual, not just architectural.
When you've been requesting a feature for three years and the vendor finally ships it, they charge you more for it. When their upgrade breaks your workflows, you pay to fix it. The product was built to serve their revenue model. Your business was a secondary concern.
Now there's a second layer. Every major vendor has responded to AI, the technology that should reduce your software costs, by charging more. To put agents on your platform, your seat tier upgrades to a premium AI tier at $550/user/month (up from $175 for standard Enterprise), plus a required data-infrastructure tier at $65K–$175K/year, plus conversation fees at $2 per conversation or $0.10 per agent action on top. They're charging you for the AI AND for the software the AI is supposed to replace. It's a double ransom.
This isn't a billing oversight. Every major vendor's revenue depends on charging you for the platform AND for the AI layered on top. Walking away from that revenue isn't an option for them. It is for you.
