Why don’t Google and Facebook use ChillingEffects to mitigate censorship like Twitter?

At the request of the government of India, Google India and Facebook have removed content from Blogger and the world’s largest social network after a court order. As Alex Kirkpatrick reported at Mashable, “Indian prosecutors are suing a host of Internet companies on behalf of a Muslim religious leader who has accused them of hosting content that insults Islam.”

If Google and Facebook used Chilling Effects like Twitter, we’d know what content they had censored in India For context, consider Twitter’s stance on censorship and Internet freedom.

While Google’s Transparency Report for India is laudable and impressively visualized, it doesn’t show what content was removed.

As far as I know, Facebook neither posts data of content takedown requests by region nor the content itself. If you know of such data or reports, please let me know in the comments
