I’m sorry to say @rolandhaeder, that your arguments are completely irrelevant.
Even if the compagny got mad, what is the problem? We would just stop using RM. We are not bound to any specific IDE. We just give away free licenses that JetBrains granted us. That’s all.
You are not developer, are you? If you are not, then I think you just should not talk about this subject because really you are talking about something you obviously don’t know. Either what RubyMine is, nor what IntelliJ is.
