I will backtrack a little and concede that it's not evidenced that the LGBA itself taking the cash, but here's its founder talking about how the wider movement she represents wouldn't have even been possible in the United States without Heritage Foundation backing https://twitter.com/BevJacksonAuth/status/115396424210361548... (not her only tweet defending the need for feminists to work with the Heritage Foundation)

I think being such a niche cause that only your notional political enemies pursuing a divide and conquer strategy will work with you internationally is what most people mean when they accuse a cause of being "astroturfed"

[For the avoidance of doubt I fully agree that in other respects, they do not share the same political views and that they are not closet hardline antifeminists in disguise]
