This is the tech version of "nobody I know voted for Nixon": FB's position in the US & Europe is very misleading from a global perspective. In the Philippines, say, Facebook is the internet. Every business runs on it. People use it instead of news. Everybody uses Messenger to chat. You get free minutes with your phone that are specifically for FB/IG/Messenger.
As someone with a Filipina wife and who's traveled many times to the Philippines, your characterization is exactly correct. Facebook is the option, not just one option. Interesting side fact: The Philippines is #1 in social media usage in the world.
By what metric?
