Vendors and their largest customers
"Oracle are so bad to work with, they force companies to invent their own database platforms just to get away.

Kinda like the old hardware vendors (IBM, HP, SUN, etc): "they force(d) companies (AMZN, FB, GOOG, MSFT) to invent their own database (and hardware) platforms just to get away."
Arrogance is vendor neutral....
