Oracle didn't do anything wrong except agreeing to support it. How many companies out there use Itanium hardware? Intel and other semi conductor companies have abandoned the hardware for the most part. We haven't even seen updates in almost half a decade. Companies that ran Itanium hardware at some point, dumped this technology many years ago. HPE plans on supporting OpenVMS/Itanium until 2022. Most of the legacy software would require a complete rewrite to run on other platforms and is considered business critical.
"If you can't fix the problem, there's lots of money in prolonging it.".
Oracle will appeal this and win, I bet. In the slim chance they don't, that's $3B more for Meg and her cronies.
