Joe, no-one is suggesting curation, hosting, indexing and the like should be done for free. (At least, I a not!) We are suggesting that the result of this work should be available to all -- including, crucially, the researchers who did the work and the citizens whose taxes funded it. Increasingly, we are seeing the author-pays model work well, with publication fees coming out of project grants.
That seems like a conflict of interest for the publisher. For every article filtered out, they lose money?
Or pay to submit and risk not being accepted anyway? Kind of a 'poll tax', where you have to have money to be heard. In principle its shakey either way, though if the fees were low enough...
