"What if I want to switch" is a valid question if your business is at the mercy of a single vendor with a history of abusive business practices towards its customers.

While I may have a selection bias, I have seen quite a lot of companies migrating their applications, successfully. Most for exactly this reason. And many, perhaps even more, that would very much like to migrate if it was less disruptive.

Yep - agreed. It's "pick your poison". No matter what tech stack you select, migration away from it is a may be a consideration. (Whether it is a JavaScript framework, PHP to python, C++ to Go, or one DB engine to another.)

If being able to easily switch technology stacks is important to your business success, then you need to optimize for that. That's not the case for me.
