When AWS and Co did provide hosting and provided it better than these guys could, now it's suddenly AWS who are the bad guys for using the FOSS software the way the license always said they could. Now we're suddenly supposed to ignore the terms on which FOSS has always been released and pick up our pitchforks against the big mean cloud provider.
Instead of sticking to the fundamental principles of FOSS (principles which they won business by openly espousing) and adapting their business to the fact that Elastic and Redis lost in the competition they knowingly set up, they fixated on hosting (on top of AWS and Co, no less!) as the business model and changed the licenses to give themselves a monopoly on it.
