Nobody is telling Linus he messed something up. Are we not allowed to raise issues, discuss and bring forth our perceived problems? "Use it as it is or GTFO" doesn't seem like the Open Source way. The problem here is that there are people telling everybody that "git is easy," "everybody should use git," and then every time someone raises a concern someone brings up the argument above. I wonder, what is your goal? Are you trying to get people who "don't get it" to stop using git? Do you think killing discussions about it will further progress? Are you afraid the interface you learned might change?
