I find those kinds of comments insufferable as well, but I'll assume you actually wanted an answer and not just an excuse to chastise someone:

It's because those of us who have learned we don't know everything are annoyed by people who still act like they do know everything. It hurts because we're embarrassed by remembering our younger selves.

guest1539on Why `print` became a function in Python 3

So, given the incredibly low rate of Python 3 adoption, how well did that "forced" change work out for them? Python 3 deserves its fate, and apologists like you aren't going to change that.

guest1539on Why `print` became a function in Python 3

It became a function because it always should have been one. However, since it wasn't always a function, they didn't have the common sense to pick a NEW function name (puts, println, write, writeln, echo, say, show, ...) and politely deprecate the old print syntax. Shortsighted and pointless.
