The above comment wasn't an example of that, though. His friend was getting medical treatment, the issue is that you can't just buy a kidney (at least not in the US), you need to find a donor.
That isn't just an outright baseless claim, it's wrong by definition. The said person had to go to social media to find a donor, which 100% matches what I descibed, and the fact that some felt this was necessary points to a broken system. It's also terrible to imagine what shady companies can do with targeted ads aimed at vulnerable people who can't find any donors.
What solutions did you have in mind?
I cant think of any other way he could have gotten exposure without having to go on tv, radio, public areas and making his case. That power of facebook ( and other social media is undeniable )
Even Wajahat Ali on CNN, who has such a big audience, found a donor off Twitter. Not everyone has the ability to reach out to Anderson Cooper and ask for help.
For every evil thing Facebook has done, there are stories like this. Having my friend alive, his family seeing him everyday is well worth it.
