But it doesn't change the essence of the argument posited by the author. The redis modules in question were originally AGPL. Redis Labs relicensed them to Apache+Commons Clause. Both Redis Labs and Mongo reacted to pressure by relicensing software.

I agree it doesn't really disprove his general story (which I agree is a trend), it doesn't have to be universal to be a trend, a very strong trend even, there can be special unusual circumstances behind redis, or it can just not yet have succumbed but be on the way, or it can just be an unexplained exception to a strong trend.
It just makes redis not a great example to choose, and it makes his article misleading giving people the wrong idea about what's going on with redis.
