I don't really see Docker having that much of an alternative - they have to figure out some way to make money and none of their other attempts have worked.
That being said, since the core docker tech is free, this will surely just cause some free alternative to DD to spring up in the relatively short term, and accelerate the move away from Docker in general, which has been happening for a while.
