In the case of JMLR it's not 10USD per-view. It's 10USD per article published. I'm not sure if that was clear from the comment above.

Commercial journals generally charge far more than that per-view. JMLR charge nothing per-view.

When open access, commercial journals will often charge 1000s to publish an article (compared to the 10USD JMLR says it costs them).

usually I'd agree, but I think academic publishing is different from purely artistic work. Research is funded up front by grants. The resulting product is a piblic good, and should be made available to the publoc with zero margin.

If the research has practical value, the authors can capture that through patents and similar systems.

I agree but one counter argument is that a lot of research is already paid for by government.
