It seems they're doing quite well on their financials by offering access to FSD as a subscription. The misconception here is that FSD is needed for them to collect data - they collect autopilot sensor data on all cars regardless of FSD or not.
A tangent to that thought... "do you want people to be financially incentivized to get into novel situations to test situations where FSD was lacking data?"
I recall Waze had some point system to help gather positioning / speed data for side roads that it would try to have you go get with icons... and those were just fake internet points.
