Can you tell me what you're smoking so I can avoid it?
I don't know where you're reading stuff like this, but in my experience Blender Users are generally very happy and very outspoken when it comes to telling people how awesome Blender is, which can even be annoying at times. Kind of like this dude that always recommends you to use Linux when you complain about a minor issue in Windows.
On top of that, you just cannot compare open source with software as expensive as C4D. People that pay for C4D have a right to complain on a reasonable level. Sure, so do Blender users, but in the end they're using something they got for free.
Overall people will always complain, even if they literally have the perfect software at their hands.
