Sorry, I didn't want to imply that they do. This would be illegal as per antitrust regulations.
What I wanted to say is that AWS using a permissively-licenced project is fine. The project should have thought about the licence beforehand and started with copyleft from the beginning on. Their problem now.
But a more general problem I see is that even if you use a copyleft license for your project, you have the risk to be crushed by anti-competitive behaviours coming from TooBigTech. It's not rare, they do that all the time and the US doesn't enforce anything. And when others (like the EU) try to do it, the US put pressure because they defend their US TooBigTech.
The latter is not a model or licencing issue, it's an antitrust issue. Now Amazon could compete with Redis without doing it illegaly, but they can only because they are so big. And the fact that they are so big is related to the lack of antitrust enforcement (it's documented, TooBigTech have all abused their dominance forever).
