I created an open-source vector database a couple months back called OasysDB. It's not a popular project but it serve a specific use case and has a small community behind it.

So, recently, someone in the community sent a link to me about a repository that after digging deeper into it seems like a blatant copy of OasysDB v0.4 (It's now v0.7). They changed all of the initial branding and information to their own branding like name, author, email, etc.

This is their repository: https://github.com/Sahomey-Technologies/sahomedb

This is OasysDB v0.4: https://github.com/oasysai/oasysdb/tree/v0.4.0

I honestly don't know what to do. I know that OasysDB is open-source and thus, free to modify and redistribute. But, I feel like this is more like a plagiarism and a bit unethical to do.

If anyone got similar experience, I'd like to hear some advice.

Thank you in advance.
