They bought an open source project, and now that the original founder has stepped away they're trying to squeeze it for all they can.
The "big corps" that you claim are using it to "pirate software in a legal way" (a) have been contributing to the formerly open source redis project, and (b) are now specifically forking it to keep maintaining it as open source.
Supermarket bills cannot be paid with pull requests.
By using BSD license Antirez has freely given it to the whole world, not the name Redis but the code. No matter how big the corporations, the cloud providers are just using that code the way Antirez intended when he used the BSD license. You can't blame the cloud providers for that.

One could probably even argue that buying the rights to the name of a popular permissively licensed project is a terrible way to pay said bills.
How is it terrible?
