Not sure what you mean, publishers are already suffering as a result of bad-actors parasitically attaching themselves to the incumbent digital advertising network.

Brave is offering publishers a solution to their dying revenue streams. First, by way of monthly grants (we give $500k/mo to publishers right now), and secondly through a better advertising model. Note, publisher ads is not presently an option; we're testing user-private ads, which are ads shown in a private tab, not owned by any website.

They get the same deal they offer consumers: take it or leave it.

Consumers are choosing to go to those websites. Publishers are not choosing to serve their content through Brave.

Their situations seem pretty similar to me. "Take it or leave it" for the little human doesn't translate to "choose among these options or leave it" for the big corporation. They can read headers. They're also running javascript in the browser itself, so we'll see something like those pathetic "please turn off your ad blocker" messages soon enough...

No one deserves to stay in business. If the model doesn't work, find one that does.
