Twitter at least will not survive. Look at their stock- its rally correlates perfectly with Trump's presidency. Trump was their bread and butter, and Twitter runs on Drama. Before Trump, Twitter was treading water as it wasn't profitable, and investors were losing patience with the company.

Get rid of the fun (ie. the Conservative/Liberal conflict), and now Twitter stops being interesting and so people start getting bored and stop using Twitter.

And Twitter is primarily dependent on the US, unlike Facebook.
