Indeed, also depends of the country, in mine Whatsapp is the most used, then Telegram used for groups.
I think most of the people has not privacity concerns, big tech knows how to exploit that vein of gold.
If I'm honest, I don't think governments agree that a percentage of users cannot be spied on, there are excuses such as terrorism, jihadism, pedophilia, etc.... to keep us all under surveillance. They are not going to allow this to change, they handed over user data to the government, when they said it was impossible for that to happen. Remember Protonmail, one of the most secure email servers, delivering user data to the government when they said that was not impossible.
