Individual ads, sure. But an equivalent null hypothesis would be "social media advertising has no effect on people," which would seem pretty strange.

There's no reason that 'X has no effect on Y' should have a privileged position in messy real-world epistemology; we don't assume that nothing causes anything in the absence of conclusive proof, we keep an open mind and make our best guess based on whatever information we have.
