This is what happens when you don't understand how gravity works. Of course there's a big conspiracy that includes all astronomers, rocket scientists, pilots who fly high enough to see the curvature and actually have to work out where they are going, meteorologists, all sailors who have avoided going over the edge and basically anyone who has actually thought about it.
The Earth certainly looks flat at local scale, but the obvious answer is not always right. Trust science (are you listening Mr Trump?).
There seems to be a trend in people trying to challenge the scientific orthodoxy. Maybe they think there really is some conspiracy, but who profits from the spherical Earth concept? Even the ancient Greeks knew it wasn't flat and they even measured it.
