You can call your local affiliate to complain:

Better yet, call their advertisers:

More indirectly, you can support the Talarico campaign (fueling a financial Streisand effect could help discourage similar moves in the future):

CBS is responding rationally (cowardly, certainly, but also rationally) to an administration that is misusing the tools of state.

Change the administration.

I think corporate media is mostly lost. We need to build something new. Pay attention to things like The Bulwark or Liberal Currents. It's really early days for all that, so who knows where things go, but people like Bezos would rather destroy media outlets than sell them to someone who would allow them to speak out against the regime.

They'll respond to a loss of business or reputational damage.

Reputational damage is a less useful tool today, when so many of the people in power at CBS have personal reasons for wanting to curry favor with the administration. So, loss of business: simply boycotting or changing the channel can help.

You can't get CBS to air it, but you can let people know not to watch CBS.
