The most interesting assertion in this video is that the facebook algorithm sends out user updates to a sample of their fans/subscribers and that the engagement performance within that sample is a key determining factor as to whether an update is shared more broadly in news feeds.

If that is in fact the case and purchasing facebook ads indirectly increases the amount of fake/automated likes included within that sample (thereby negatively impacting the overall engagement metrics on your posts) then the purchase of facebook advertising has the side effect of diminishing your ability to organically drive traffic and engagement.

To put it another way. This would be like if buying Google Adwords advertising not only got you fake/automated traffic, but also simultaneously decreased your organic, unpaid search rankings.
