To that point, the people who submitted to the journal did so knowing that it costs money to access, it wasn't as if they were tricked into contributing to a private pay-wall journal.
For most scientists there isn't another system, and certainly when the system was established nobody was envisaging a time when publishers would make hundreds of % markup on every access of a paper. The prices reflect print publishing costs and the historical lack of a cheap distribution system like the internet. Now we have a hangover where people's careers are judged on their ability to publish in high-impact journals, all of which charge several thousand pounds extra to make the paper Open Access. So we're not tricked, but we do it under duress.
