Alternative title: Redis is no longer open source but rather source available.
Even Microsoft Windows is source available if you are an important customer: https://www.microsoft.com/en-us/sharedsource/default.aspx
A bit more public and open to anyone is Unreal Engine's source code: https://dev.epicgames.com/documentation/en-us/unreal-engine/...
The majority of people on HN are programmers, the majority of people not on HN are not programmers, the majority of programmers are not on HN.
I can't speak on what the majority of programmers think. Isn't the opinion of people in the open source community the interesting one?
I mean sure, the more upset reactions from the more invested parties are the more interesting ones. I just take issue with people fighting to use a more-incorrect, less-used definition which serves no purpose other than to try make entities like Redis look bad.
Open Source has core definitions around the freedoms (the "speech") allowed to people when making use of that source code.
Source available makes the source code available for free (the "beer") along with certain specific freedoms, but not all of the freedoms that would be required to be Open Source.
Whether or not you think those missing freedoms are important is a matter of personal opinion, I suppose. I think they are, which is why I try to avoid source available software if there is a reasonable open source alternative.
