McGill and you got it backwards. Open Access has a quite clear definition.[0] Publishers have co-opeded the term and dopne everything to confuse the issue. All the so-called open access colours are mainly publisher made, to water down the true OA definition.
Sure, but none of that matters if the big publishers are the ones gobbling up the money anyway. For some reason it’s better to pay them a ridiculous amount of money to host PDFs than it is to pay for subscriptions? What’s the difference? Most university libraries have always had access to all the important journals and anyone can go there and do their research. The whole idea that subscription is evil and OA is good is ludicrous. We’re paying the same amount of money (or more) only to get a much, much shittier service, and a torrent of absolute meaningless “research” that only serves to drown out the good ones.
PS: And by the way, if you say that “not every country has access to these libraries” then think about whether they have money to pay for APCs.
