That's not a way around publishing at the established venues, it's done in addition to it. Everyone still submits to the established journals and conferences because this is what is being evaluated for career advancement and funding.

Is not the chief practical problem that access to knowledge gets barred in a pay-to-read system. The trick is one patch against that chief practical issue, which can be for these purposes separated by the systemic issue.

I agree: it helps a lot with the practical issue of access to knowledge. But from a taxpayer's or academic's perspective it wouldn't hurt to also eliminate the exorbitant publishing/licensing fees.
