It doesn't sound like the reservations of the people in charge of Python are about funding; I don't think it's as simple as "pay them $1m to merge the PR and then pay them salaries as they maintain it". Unless the assumption is that the people in charge of Python would take a bribe, I don't see how large companies could somehow magically make this happen with money short of just forking Python and trying to maintain it themselves, which would burn a ton of goodwill and likely not even win over the community.
