Well, we learn from other companies' mistakes... we had a chance to observe how did it go for VMware with vSphere Enterprise Plus
did not work very well. May be they made some extra money, but their image was a bit spoiled over this too.
And in addition, how else we can thank all of the customers who sticked with us from early days, and who helped to make this product what it is now. There was certain risk, but you made the bet on us, and apparently your bet won!
