Most publishers offer "Gold Open Access", which is "authors pay" instead of "readers pay", and of course the price is decided by the publisher…
This is not what Open Access means, and it doesn't solve the main problems.
Diamond Open Access focuses on the real problems.
1- It should be free to publish, free to read, free to reuse. The Diamond Open Access model implies free licenses such as Creative Commons BY for articles and data.
2- Rather than being owned by publishers, the journals have to be owned by their editorial board, which itself has to be a legal entity of some sort. This would avoid problems such as prestige inertia which forces researcher to publish with asshole publishers: if the scientists actually running the journal own it, they could have switched to open access and/or to a different publishers when needed.
Apart from that, we of course have to fight against bibliometrics…
You may have a career, but i doubt that qualifies one as a scientist.
