Why not use $1,000,000. to promote regular vegan food manufacturing?
What person who says they couldn't go veg'n because they like meat so much is gonna want to eat in vitro meat?
One- they would probably just eat "humanly raised" meat, but can't afford it.
which leads to Two-they wouldn't afford invitro meat either!
I would expect the promotion of invitro meat would cause even bigger demands for the real thing. It would cause a comparison in taste and cost, and concievably undermind many peoples attempt to avoid it.
