I think there is an implied frustration with the fragmentation of "the open source effort", which is ... understandable. It should have been written more diplomatically. It seems to me to be a pervasive problem on anonymous forums.
I think it's a completely fair thing to politely ask why people are spending their time on this. Surely they have somg goal in mind.. Maybe they have some bigger goal, like commercial OS's tuned to the RPi or something that only BSD systems can do? Or maybe it's something simpler
This is half true. People will go out of their way to make the organization better if it make their jobs easier (ex: switching to more modern easy-to-work with technology). But if for instance the project is going in a wrong direction, most of the time you have no good reason to fight to change things (and yes, it's fight b/c often it's about changing opinions and demonstrating repeatedly that things needs to be done different). So sure, do your duty and voice your concerns but at the end of the day just go with the way the boss decides. This is called delegation of responsibility and something a lot of people don't grasp. You need to cover you ass to stay sane.
Except this big catch is that employees are compensated for the improvements they bring about. That basically never happens in a typical software company. Maybe if you keep bringing in important changes someone will notice and maybe you'll get stock options or you'll be promote to management
