How can Oracle still stay they are the #1 development platform

Oracle is a facet of the devil.
Change my mind.

Because they are. I have yet to find a place in which the JVM does not say hi in one way or another on an enterprise level application/system.

As evil as Oracle is, them dudes are everywhere. And Java as well as JS and PHP pay the bills, so I don't care if their devs write the JVM using kitty blood as their fuel.

I love my money.

@jespersh but we cant forget that many of these devices are destroyed after 3-6 years.

DONT FORGET THE SIM CARDS

Java is #1 development platform, not Oracle.

Android --> java
Sim cards --> java
Atm --> java
Small old windows programs --> java

Maybe they are though, considering the amout of Android devices, CD Players, IoT devices, maybe even business machines running java.
