‘Up to half’ of European papers to be open access under Plan S

>"The paper estimates that about 90,000 papers funded by Plan S supporters which are currently published in hybrid or subscription journals would need to be “rehoused” if the titles did not flip to full open access." Not quite. Hybrid or subscription journals have another option if they wish to retain Plan S authors. They can allow unembargoed deposit of the accepted manuscript version in repositories with a CC-BY licence. This option is a good deal easier than flipping in the majority of cases! Royal Society journals and Microbiology Society journals have already enabled this.
