Academia carries with it a larger amount of authority than a random programming forum. Students have the expectation that the academic staff is generally knowledgeable and wise and what they say in all probability is very important, has to be remembered and followed (even if you don't quite understand why yet but perhaps you will in the future).

I don't think "Academia" that doesn't teach critical thinking and only practices its authority over students should be called academic institution.

I agree. And yet, this seems to be the rare type. Often it's just a few people in the staff that are trying to do things the right way, for the others it's simply a nice job (with few responsibilities and seemingly no obligations). That's what I've been trying to get across. Teaching is a sensitive job with far-reaching consequences, yet more often than not people don't take it seriously and don't care what their students will carry with them into the life when they leave the walls of that academic institution.
