You seem to very creative in coming up with flimsy excuses for facebook :)
Which other fault-free organizations can claim to have settled with the FTC for privacy abuses, had their CEO forced to testify in front of the US congress and be questioned in a case of election manipulation, facilitated genocide, purposefully manipulated people into feeling depressed and many others?
There's an entire book written about the tremendous negative effects of companies like facebook on society - surveilance capitalism.
When comparing all of the above with the benefit of allowing various average joes to stay in touch with their family, which can very well be done over e-mail, phone, or any of the gazillion other social networks, it makes the latter mean precisely nothing.
At this point facebook would have to literally cure cancer for them to make up for their negative effects.
