Sorry, I didn't mean it to come off as a statement. It says that there's an online IDE, so it was a question; I unfortunately used a '.' to end the first sentence because I had an 'etc.' at the end.

It's seriously a question; and if the answer is yes, then the following statement applies (the one about attracting talent).

But yes, it came off pretty cynical and sarcastic, but if someone is going to try to force me to use a particular IDE, it would piss me off (and the thought of it did too).

If it works anything like OpenShift 3's on premise product, and I see nothing that says it doesn't, you can use whatever IDE you want, but the deeper you get into customization, the less "special sauce" you'll get. Maybe clippy won't pop up and say "hey, it looks like you're trying to use an out of date library!" if you're editing in vi and checking in with git or whatever.
