I am supporting diamond model journals (free to read and free to write). It is extremely important to have high-quality journals without entry barriers, especially in the context of money-making corporations which are using research articles as their merchandise. I am usually not publishing papers in journals with high prices per one site of the text (except the cases of very reasonable wishes of my co-authors).
I am regularly publishing in Electronic Research Annoucements in Mathematical Sciences and I wish to continue this tradition.
