Of his ten films, 6 of them seem to be available (from sources who seem to own some kind of cpyright to official copies) for watching online.

The idea is not to hurt the commercial prospects of these films. I’m sure Sivan would benefit from films like Anantabhadram and Navarasa being available for people to view online, on demand.
