Agreed. It would be in the interest of citizens of most countries to block these apps. IMO, any company which is present in a country must be beneficial to the average citizen of that country. If a company is not beneficial to the average citizen, then it should be banned.

I think the biggest issue with these apps is that they monopolize attention away from local products and local jobs. They destroy national economies. Each country must have their own search engines and their own social media companies.
