At the end of the day, open source projects need developers... and developers need to eat. These license changes have been forced by the business reality of larger cloud companies capturing all the value created by open source communities and leaving OSS developers to starve. Who deserves the value created by Redis? Antirez and the Redis Labs developers? Or Jeff Bezos?
No, they haven't, because the “big industry players capture the revenue, while open source devs mostly work for those players, either directly or through sponsored projects” isn't something that started with the cloud; it's why Linus Torvalds isn't a billionaire.
It's forced by firms wanting the economics of classic proprietary software and the PR benefits of F/OSS, in many cases, apparently, because they have investors who bought in to F/OSS-based endeavors based on expectations that were unrealistic ab initio given the economics of the industry.
