Unfortunately, when the open access way was started, the objective was ethical: Open Science! but now with the emergence of hundreds of new open access journals (especially those from predatory publishers from India) that force authors to pay for publishing their efforts! this humanistic objective is not realized! If really we want open science then it is required to waive the fees to all authors from developing countries. Few journals from respectable publishers ensure that (sometimes only a reduction)! But most of them reject any request for a waiver !. In addition, don't you think that these fees are in the majority of cases overestimated?!!
Open Access must be a choice not an obligation for all journals!
