While most of the points in this post have some sides of being true to some extent, but its general perception is off a true objective manner.
Current Iranian academic body have more merits than 34 years ago (even despite very high rate of brain drain that happens in Iran), simply because of changes in time, academic institutes expansions and population. As an evidence you might refer to its recent years growth:

At the same time there exists publishing troubles for those who do research in local-context social science disciplines in languages rather than English. This can be more problematic, if they work in theology or fields similar to that.
And the sanction of Iranian authors (actually sanction of editing their works, specially without any other non-Iranian author in the list) is a true story.
At the end, the quality of ISC index or the possibility of abuse cases can of course be a matter of concern, but these do not reject the need for a localized indexing system, regarding the current cultural and political settings and barriers.
