Yeah I think that's awful that they do that. I was specifically talking about in the US, where it is easy to use a competitor. (The comment I replied to was also talking specifically about the US: "Free speech in America...")
Facebook has pulled similar tactics in the US also : https://www.wired.com/2010/11/google-facebook-data/
Facebook has been abusing it's massive size to block access to competitors using their Facebook Zero program : https://en.wikipedia.org/wiki/Facebook_Zero
From the page :
> In 2015, researchers evaluating how Facebook Zero shapes information and communication technology use in the developing world found that 11% of Indonesians who said they used Facebook also said they did not use the Internet. 65% of Nigerians, 61% of Indonesians, and 58% of Indians agree with the statement that "Facebook is the Internet".
