What I intended to say exactly is very simple. The post which I originally replied to states that the guy intends to basically copy journal articles behind pay walls and put them on some site where everyone can access them for free. I stated that such a thing would firstly be a breach of copyrights, secondly is unethical, thirdly there is no reason to do it and I tried to give my reasons which are summarised below.
It is nice for sure to get stuff for free, but I suggested that someone would have to pay for it. If it would not be the current institutions and professionals which pay for it, then the money would either come from the research funding, or professor's pay, or higher university fees for students as professionals who work in that field need not buy such articles, but to publish such articles requires money which universities would need to find from somewhere.
I do not know if an editor is paid for editing, or a peer reviewer for reviewing, but many of these journals are printed. You can find most of them online but even there there is much overhead, such as customer support, people to add the articles online, format them and all the rest.
Currently, professionals pay for this infrastructure. If you are a lawyer for example, you would probably need access to these journals as the law changes all the time. So too if you are a doctor I would think, or a psychologist, or historian...
Universities pay for it too, but students do not directly.
You can argue that they charge too much, you can argue that the system needs to be reformed, but I was trying to argue that the journals do not need to be free. That is so because any given journal interests a very small number of people and the general public would not understand them or have any interest in them. If one is doing computer science, ok they might be interested to read one article or two in the field of medicine which might be of a general interest, such as the article in point, but generally, they wouldn't be interested to read articles from a field in which they do not operate.
Therefore, to conclude, as the public would not really have any benefit from having all the journals for free, I would rather the professionals who have an interest in the journals provide the funding to support them.
