Therefore, it is clear that Google's policies must have changed, and that they now apply the new policies to old advertising contracts. And CD is not alone. Google and YouTube now seem to reject Christian advertisers pretty consistently.

Here's the exact reason what Google accuses CD of:

 - Makes false statements about your identity or qualifications
 - Uses false claims or claims that entice the user with an improbable result (even if this result is possible) as the likely outcome that a user can expect
 - Falsely implies affiliation with, or endorsement by, another individual, organization, product, or service

The times are changing, and Silicon Valley and other big tech are clearly not on our side.
