You're using the phrase "MBA thinking" to mean "making decisions based on your personal use case and identifying solutions which match".

I'm not sure how this is a bad thing. I don't run Linux to run games because Windows is a better supported platform for running games. I'm not "looking at past numbers", I'm looking at the situation in front of me as it exists, setting aside my personal feeling on what might have been and instead focusing on what actually exists, today, for the problem I am looking to solve today.
