This is, of course, how oracle and others earned its reputation. These things and worse really happen. Obviously nobody wants this when they pay for better.

I agree with another commenter that in the long run, it'll end up as OSS + support from a 3rd party consultant or vendor that is commercially aligned with your success.

It has taken a very long time to convince most IT to behave like a branch of business that can create new value. Once that shift happens fully, we'll see the "keep the lights on at all costs" mindset change a bit in favor of truly measuring ROI and true total cost of ownership. For most large companies this has never been done.
