As I said very early in this thread, I oppose the Commons Clause. I don't agree with the statement you quoted either; on the contrary, I would present NextCloud - a company which builds a product, does *not* offer it as a service, and encourages others to do so - as a shining beacon of "the spirit of the open-source community".

But what's also in the spirit of the community is to avoid biting hands that feed you. Thus, it is very rare to see an Open Core company finding Open Source competition to its proprietary extensions.

If you refuse to see a difference between "using a project without contributing back" and "actively harming a project using overwhelming market power", then you will see no difference between what Redis does and what Amazon does. I do see a difference.

And that is why, while I think what Redis Labs is doing is wrong, they have my sympathy.
