The general public (especially in developing countries) don't understand this at all.
In many countries facebook/messenger/whatsapp is unmetered thanks to facebook subsidies, which makes 'giving up your rights' the cheapest way (sometimes the only affordable way) to pay for a service to communicate with people.
Facebook is bundled with pretty much every Android phone ever.
People without facebook accounts have profiles, they're just not generally visible.
They've put a shitload of money and effort into forcing themselves into the position as a totally pervasive social arbitration platform, where the social cost of opting out makes it impossible even if you ignore the fact that your friends are probably still participating and happily handing over your data for you.
What's bizzarre is how people who do know these things still seem to expect 'perspective and common sense' from a totally uninterested and mostly uneducated public, and how people who do know these things can ignore just how creepy and predatory Facebooks practices are.
