@aral This might be a bit of a weird take on this, but I think the most concrete thing most of us can do against this is use and encourage the use of ad-blockers.
We can't compete at scale with this sort of money. Free services will always trump donation-based or paid services, because that's what we're used to as consumers.
We *can* however try to make this industry totally not worth it for VCs to invest in. And this is where ad/tracking blockers at a massive scale come in.
