Fyi... in response sibling comments with phrases such as "proprietary service" and "vendor lock-in"... I have no direct insight into the motivations of Fermat's Library but based on past interviews, the brothers Luís & João Batalha are 2 of the 4 founders and they said it's a side project and not meant to be a for-profit service. They're paying for server costs on their own. They also make the platform software (Margins) that Fermat's Library runs on free for other universities to use. Their "day job" is a B2B sales marketing service which has nothing to do with science publishing: https://amplemarket.com/about https://amplemarket.com/about So the analogy would be Hacker News website being a "side project" of Paul Graham and YCombinator offering free access to some weblinks aggregation. It's understandable that other commercial services that are paywalled make people distrust the future of a supposedly "free" service. I guess the same could have been said about Paul Graham back in 2007: "How do we know that PG won't paywall the HN website in the future and lock us all out of our free contributions of thread comments?" Nobody but PG could have answered that hypothetical question and yet... here were are. Yes, anything can happen and it's possible for the brothers to backtrack from their words but it would make them look bad for little gain. I think their intentional profit company Amplemarket has a better chance of making a lot of money than an academic annotation service. Perhaps we can use that in our Bayesian Probability of trusting/distrusting their future plans.
