Yes, there is. Big Tech firms like Google and Facebook are so BIG that their refusal to provide service is akin to denying you access to the public square.
Break up big tech as monopolies, create a much more “diverse” marketplace, and you may have an argument.
However, that’s not enough. They have to be prosecuted for shutting down conservative alternatives. They criminally colluded to kill rivals so that they remained dominant.
Example 1: Mastercard, Stripe and Paypal colluding to kill Patreon rivals Subscribestar and Freestarter, because the latter two wouldn’t ban people liberals didn’t like. They killed Freestarter, and Subscribestar caved. That’s criminal collusion by financial and tech firms to shut down businesses that don’t agree with them.
Example 2: the killing of social media startups
Remember Gab.ai? The Twitter rival? Google has a special data mining relationship with Twitter. They also share political views along with other liberal big tech firms. Then they colluded together to kill it. Banning it from Apple and Android (google) app stores. Banning its ads and preventing it from being discussed on social media.
A cake shop not wanting to bake me a cake isn’t an issue because I can go to a dozen other places. The several big tech firms ARE 99% of the market. And we can’t even get the market to create alternatives because Big Tech colludes to kill them - repeatedly.
Break them up as monopolies, prosecute the executives for violation of civil rights and trade policy. THEN we will have true economic and political freedom.
They are, in fact, a monopoly, and should be treated as such.
