It depends on how you read part of the EU statement, but there's a note about not accepting "the hybrid approach". If this refers to hybrid journals, then that would be the barring of publishing in large numbers of journals.
So if commercial services can add something -- on top of full, open disclosure of research findings -- they're going to make that unlawful? That seems strange: what does the public gain from that?
No. There can still be commercial services, commercial for-profit publishing, etc. What they're saying is that simply they don't want to publish findings in subscription journals.
> what does the public gain from that?
The public and researchers gain permanent access to the research output regardless of which publisher, what deals are in place, where they are or whether their library has a current subscription. It allows researchers to do work analysing the content itself too as they'll then have a licence to do so (useful if you want to analyse, say, 10M papers). Research output reported in the news will be available for any interested party
The downside is that instead of publishing for free and then the readers paying, the payment model will be flipped to upfront payment for services and then free access.
