Tech companies have been doing this for the last 10 years or more and people didn't learn it yet. They seduce you with a generous free tier that is so generous that you can even build production stuff for free. They have only a few paid features in a cheap tier that you will probably need only when you app is big enough and making you money, so you don't see any problems and go all in. A few years later, when the market have adopted the tool and the tool is the "go to" tool, almost the de facto standard... BOOM! They change their pricing model and it gets really expansive, but the you have two alternatives, pay their price or change your app. You usually pay their price because change your app is too expensive: you need to tell your boss to change the app and your boss needs to tell their boss to change the app; the boss of your boss will blame them and your boss will blame you. NOBODY wants this happening.
