The thing about social media companies is we all have one important power. Just uninstall the app. I agree they suck in so many ways.
Kids though… There are a few things that make me glad I do not have any. Cell phones and social media. They just seem problematic. Not sure anyone under the age of 16 should have either or be on an unfiltered net connection.
Really no one that does not know the standard net rule of block and move on and never share PII should be on the net. I would hope that a 16 year old would know that but maybe not.
