I’ve been wondering that too, since I found the campaign to pester my kids constantly. Tried to clean their browser history and change the algorithm but it keeps popping up.

Basically it’s a disgusting attempt to brainwash kids.

From Wikipedia: https://en.m.wikipedia.org/wiki/He_Gets_Us

The campaign primarily targets younger demographics and religious skeptics

He Gets Us has faced criticism over the extensive spending by the campaign, its donors’ support of anti-abortion and anti-LGBT groups, and disputes over claims that the campaign is apolitical.

most of the individual donors who provided the money have chosen to remain anonymous.
