>I would argue none of these are free, because they use/sell your data
In a technical sense sure, but from the user's perspective it's equivalent to being free since the user doesn't have to do anything different compared to if it was a free service.
>meta burying their own studies on their affect on the mental health of teenage girls just to continue making their profits
Are you referring to the study that said that Instagram on average improved mental health in 12 out of 12 categories for teen boys and in 11 out of the 12 categories they were surveying for teen girls (the exception being that 32.40% of teenage girls with body image issues felt Instagram made it worse)? It was internal research which is why it was initially kept internal.
