GitHub - Significant Social Media Intermediary?

Disclaimer: I am not in defence of any of the indecent content posted by Indian users on GitHub that have targeted women.

I came across an article posted on where the author argues that GitHub is a significant social media intermediary, as per the IT Rules, 2021 (as of date, partly stayed by the Hon’ble Bombay and Madras High Courts respectively, and listed before the Hon’ble Supreme Court). In these rules, a social media intermediary is defined as one which “primarily or solely enables online interaction between two or more users”.

GitHub not being a social media intermediary by this definition, should not be subject to the same requirements as this class of intermediaries, right?

FWIW, I think the Information Technology (Procedure & Safeguards for Interception, Monitoring & Decryption of Information) Rules, 2009 provide adequate mechanism in the form of judicial redress and complaints by aggrieved users against putative intermediaries (transparency of blocking orders being a distinct issue, however)
