They don’t want to be contacted. I don’t think we have any moral obligation to supply them with medicines or technologies that they don’t want, even if they would objectively improve their quality of life.
No they will probably never advance substantially in technology. To get to where the developed world is today took centuries of industrialisation and trade.

I use Lemmy and moved here in protest of the Reddit API pricing changes, but I’m not entirely opposed to other forms of social media. I’m aware of the privacy implications of a lot of them, and try to manage my use of them accordingly. I have Instagram and Snapchat etc which I have used for years to keep in touch with friends. 90% of my friends use Facebook messagenger to IM and I think that’s pretty standard in Australia. I can’t justify cutting that many people off for privacy reasons. I understand the privacy implications of using these. It’s a balance. Social media can be bad for mental health, but a lack of social connection can be too. You need to find your own balance.
