Exactly this. Want people to publish in open access journals? Make high impact journals open access. People are going to publish in whichever journal most helps their career, not whichever journal has the best licensing scheme. The reason traditional publishing has failed is because even at the highest tier universities there is not universal access to content or even access to the majority of content. Sure my University will buy me whatever paper I want, but I don't want to wait a day to get a paper and then discover that it is not actually pertinent to my work when I can get it on scihub in five minutes without having to fill out a request form. Until there are bundled services a la Spotify which provide access to almost everything, scihub will continue to flourish. The issue has very little to do with price and much more to do with convenience to the researcher.
