Yeah, it is true for some definition of "a lot", but still is a minority, a number of countries much smaller than what should be according with that opinion. Nonetheless, it is funny how before US had the urge to do the same to control which parties should be allowed to mass spread messages within its borders, the common sense and default ideology was that those bannings in the Internet were a proof on how evil and dictatorial these countries were, in contrast to how free were the USA. But unsurprisingly, perceptions and ideologies always change with time, always based on how convenient and useful they are for the powerful.
You cannot be dogmatic and unrealistic. When adversaries are systematically abusing your own systems to influence your society repeatedly, you need to take action. This is far less action than say China is, which not only doesn’t allow TikTok as is on their own population, but has banned all us social media for years and years.
Ok, another metric to look at is population access. If you combine population of China, Iran, North Korea, Russia, Myanmar, etc it’s more than 2 billion people without access to American social media platforms.
