On the extensions page, it simply says “This extension violates the Brave Web Store policy.”.
What is Brave Web Store? I don’t think such a thing exists?
There is no explanation why. I think this is both intellectually insulting to the users (implying that we are not smart enough to comprehend the reasoning behind the removal) and actually weakens the security as users ore on their own when installing an extension from the source from https://github.com/rahiel/archiveror, not knowing if there is actually any problem with the extension. As far as I can tell, there was no extension takeover or recent malicious commits. An extension transparency log similar to CRL would be a better solution.
Users should be able to have control over the browser that claims to have respect for its users.
I would suspect this is referring to Chrome web store. I noticed no commits in 2 years, Not sure how stable or buggy it is, there has been many changes to Chrome/Brave source code.
Try to install the same extension in Chrome also, I would suspect the same error would come up
