Unfortunately this level of incoherence is almost universal on HN and similar forums. You'd have to be completely out of your mind to install this extension, but people for some reason believe they can install privacy. They got whipped into fearing nebulous online actors so much that they'll download FSB rootkits dressed as VPNs. The minimal set of actions a rational person would take after realizing they've been tricked into installing this extension is setting their entire PC on fire and then running it over with their car, while moving all of their bank accounts to new accounts, in person, and changing all of their passwords using a brand new device.
