I am not an MIT researcher however my university dropped Elsevier at some point and I think generally the experience and sentiment is similar across universities and fields from the admittedly small sample size I have.
It makes things more annoying on some levels, but between the two sides of university library versus Elsevier the large majority of scientists agree with Elsevier being wrong so the annoyance is generally acceptable. Ideally this entire system changes for the better but we can make it work in the short term. Not to mention that even before this we often ran into journals we didn't have access to, so some of these annoyances would have existed regardless.
