This. Besides "diamond open access" some in the open access community try to establish the "fair open access principles" [1]. For a journal to comply to these principles means that they are owned by the scholarly community, free for authors and readers, authors retain copyright, and any other costs paid by the journal to a publisher are low and reasonable. We have started to put up a network for journals that follow these principles with the "Free Journal Network" [2] to promote and support each other.
Concerning other comments on funding, I wanted to add that some journals don't need much money (hosting is basically free, workload shared well by editorial board). On the other hand funding can and does come from universities and their libraries (money not spend on subscriptions), research institutions, museums, and donations (sometimes seen as volountary APCs by those who have the money from grants).
