As other's have pointed out, but it bears repeating, this is not a thing.
There is actually nothing particularly shocking about what Redis is doing here; it's been done by many open source companies in the past and present and nobody cares. Yes, it can be considered a somewhat less tasteful way to make money from an open source platform but not enough to get a big thread on HN.
What they did to stir this debate is confusingly and unnecessarily tie this move to open source licensing and "commons" naming. This is what brought all this attention to something that is otherwise not very controversial.
