Many have no idea the sort of things their bishops have said and what sort of damage it might have done or might do.
I’m not sure what advantage this site offers, though.
As
@LeafByNiggle already pointed out, we can know what our bishops are saying by going to the website of the diocese. If you want a website to collect links to all their statements and maybe even make it easier to search by specific topics, great. But this site isn’t doing that. It’s scoring them by how well they align with what LifeSite news wants of them and appears completely open to abuses such as cherry-picked quotes. They’ve effectively turned a decent idea of a centralized database into a gossip-promoting site.
And outside of the gossip, I’m not sure what this offers to laity. Short of prayer, which we should be doing regardless, or armed uprising, which we shouldn’t do no matter what, there’s not much we can do. Sure, we could get an understanding of what to pray for, but that can be accomplished without all the gossip-y aspects of the site.
Beyond that, though, we can’t vote them out, because the Church isn’t a democracy, and while we can call for resignation, that power ultimately does not lie with us and is bound to be ignored if just gossip. Many of us also aren’t in a position to just pack up and jump around diocese at will, since a diocese is tied to a specific region where we also live, work, and/or go to school. I can’t pack up and go to the East Coast at a whim because some bishop over there is scored better than any bishop on the West Coast. Unless we live on the border between two dioceses, we can’t “diocese shop”, to borrow the Protestant term of “church shopping”.
In general, this just comes across more like those political sites that rate candidates in an effort to help us vote according to our ideals, just without the democratic foundation that those sites are operating under. Maybe LifeSite News does want to democratize the Church, and this is them attempting to put that into practice, but that’s absolutely not the right response we should be having.
