Copycat is a bit of a stretch here imho, considering it's in different language, and even the general architecture. But I agree they are very compatible on the protocol level, which they used as an advantage as people don't need to rewrite their code when they migrate.

It's not a stretch. They literally copied the java code and re-implemented it class-by-class with Seastar/c++.

It's literally in the ORIGIN file in their repo: https://github.com/scylladb/scylladb/blob/dc375b8cd3e8c7e85d...

Yes, I understand they looked at the source and re-implemented a bunch of it when they started 10 years ago. But in the result it's a very different code. I mean, it's 45K commits so I believe they implemented things by themselves in majority of those commits. I guess we just have different understanding of the copycat term.

Youre not far off, just use your original sentence and acknowledge that Scylla isn’t the OSS here, its the company that came in, forked a volunteer driven project, and tried to pretend its theirs:

> Or more often companies with money come to fork an open source project from the developer, and continue pretending it's their own now.
