Somebody who is too lazy to choose a good variable name in IntelliJ would also have chosen a bad (or even worse) variable name without the tooling. I don't buy that argument.

For class names it might be true that long compound names are driven by auto suggestions from the IDE. But I'm wondering if they're really as bad as their reputation. Somehow it's similar as for variables. You can still come up with more meaningful names if you want but I admit that auto suggestions do more harm there.
