My collegues - at least a few of them - might believe that...

There are, literally, in the IT landscape, that actually don't know better as they were raised on proprietary bullshit start to finish. Hell, even I have an ECDL cert. Does nothing, just proves that I can work with some closed sourced things but apparently it makes some bosses happy o.o'

It's up to us to help those poor souls see the bigger picture. Gently.
