Vendor lock-in is not always a problem. Imagine that you have a situation where you can either throw one engineer at it to create a custom solution or buy an existing one that locks you into their service offering? What would you choose? It is not always clear-cut, but it is better to buy simply because employees are not permanent in most cases. After they leave, there will be zero support.

If you treat them right, why would they leave? You are just planning for abuse in this case, which no amount of tooling will make okay.
