Let's just recap
>"I read the post and it’s not clear why it’s not MIT licensed. Why not allow attempts to “create proprietary distributions?” That’s what open source would allow, no? "
Your "That's what Open Source would allow", clearly implies anything but MIT / BSD license are not Open Source. Hence why people ask about Linux, which is Open Source but copy left aka non MIT / BSD.
>Edit: Linux was always GPL, Redis was not, so I don’t see the relevance.
Your first sentence implies GPL are not open source, the relevance here is why the parent ask "do you think Linux as Open Source" or happy with it. And:
>My happiness with Linux is irrelevant because Linux to my knowledge was not re licensed to be more restrictive.
Your happiness with Linux contradict with the first "quoted" sentence to what a lot of people think you meant.
Just in case, I am on the BSD / MIT camp but what you wrote create a lot of confusion.
