"a huge slice of Facebook’s income comes from pharmaceutical companies, so it bans dietary supplements from its shopping system"
Wow, pharmaceutical companies do seem to spend a lot on advertising on television and internet. Surprised Facebook would ban supplements though because of it. Are they scared of turning off the pharmaceutical companies as advertisers? Seems strange to me as they would probably advertise anyways.
Good point on how much time people waste on FB. You go on there and then get sucked into all the news articles and videos being shared. It's never ending haha.
Yes FB totally changes what appears on everyone's timelines as well as banning advertising that offends their main sponsors (like the sickness/vaccine/drug industry). Posts about Vitamin C for example, are quickly buried under 5 tonnes of elephant dung.
