Why does Open Philanthropy not start granting out $1M/yr to the Long-Term Future Fund? Hopefully these opportunities would beat Open Phil's last dollar!

It seems like everyone affiliated with the EA Infrastructure Fund is also strongly affiliated with longtermism. I admire that you are going to use guest managers to add more worldview diversity, but insofar as the infrastructure fund is funding a lot of the community building efforts for effective altruism writ large should we worry about the cause neutrality here?
