Agreed. This deliberate stalling of the new engine, unless you purchase, is just a reminder of the old days of  Microsoft being the big bully and being jerks to all their customers.

As it stands, I have no intention of giving you more money, so all that happens now is that resentment for your bad behavior leads to these (and numerous) complaints, which is sad.
