>None of these things are free my friend.

I have not paid a single cent for any of them. Many of them I'm even free to change it however I like and even release my version as a fork.

>Even then, bitching about functionality and features would be entitled.

If you think Linux or ANY of the software I listed would be nearly as good without users "bitching" I have several bridges to sell you. The alternative is to pay a whole bunch of people to test every aspect of the software to find bugs, missing features, minor UI quirks that could be tightened, etc. FOSS only works because of us "entitled" people writing git issues or contributing code when we know how to fix the issue.
