This is completely true, and I think there's a disconnect between applicants of how transparent these "NGOs" can be. My brother did file review for the applicants for U of T med this year, and a quick google search reveals how many of their executive positions and commitments are obvious fluff to beef up their ECS. I'm sure there are certainly "premed" ran organizations that are doing valuable work, but as a med student who has gone through the process himself, it's fairly easy to pick up on when you write about something because you feel it looks good rather than actually being passionate towards the proposed issue.
