This sounds like a horrible idea.
1. It deliberately replaces some versions of libraries with different versions. That's a feature I could do without.
2. The use of integrity hashes on cross-origin resources breaks Decentraleyes[0], and it's not fixable without browser changes.[1]

And I'd have to trust substantial permissions to an addon from 'nobody'. I don't believe in mandatory real-world identities but at least have a nick with some street cred :) Trust is important with browser extensions, just look at the news today about Nano Defender being compromised and spamming Instagram likes: https://github.com/jspenguin2017/Snippets/issues/5
Just saying, this is something I'll skip for now for the above reasons, but I'll keep an eye on it.
The developer of this extension doesn't have that.
This can be mitigated by disabling auto-update functionality and insisting on reproducible builds.
edit: What I originally wondered was what was meant with the "RIP karma" comment by the parent?
I asked this the other day on a similar comment, and the best they could do is critique Moxie for having a savior complex
seems to be unmaintained/inactive.
