You are being downvoted for calling IDEs and text editors legacy, which is seen as signalling and not contributing to the conversation.
To spell it out for you, my comment was mayhap a bit more sophisticated for you to comprehend. I was not talking about "content" but the nature of the "content" within my comment and how one irrelevant adjective "legacy" was taken out of hand because it offended you. Why did it offend you? Probably because it's true.
