If Elon Musk buys out MSNBC, all the advertisers will say "Fascism!" and drop MSNBC. All the cable carriers (Comcast, Spectrum, Cablevision, etc.) will drop MSNBC as a channel.

The only thing that MSNBC owns that's worth anything is the contract with cable companies to carry the channel. All of those will be terminated after a Musk purchase.

Right-wing alt-news sites like OAN tried to get cable providers to carry their channel, but weren't able to get anyone to carry their channel, even if they charged $0 licensing fee.

Shortly after purchase, MSNBC will become an Internet-only broadcast channel, losing most of its audience.

Similarly, they're pushing Bluesky HARD right now. Remember 10 years ago when every celebrity said "Follow me on Twitter!" or "Friend me on Facebook!" That was all free advertising for Twitter/Facebook, which is how they got huge and near-monopoly status. Now they're pushing Bluesky. All the normies are going to leave Twitter for Bluesky, which means Twitter loses most of its value.

Twitter is going to be just a right-wing echo chamber like Gab.

A website has two choices:

Censor right-wing viewpoints, so it becomes a leftist/commie/normie "safe space". Then you can get advertisers, investors, and mainstream media promoting your product.

Don't censor anyone. The leftists/commies get offended and leave. You won't be able to get advertisers, investors, or mainstream media promotion.

Any "free speech website" will degenerate into a right-wing echo chamber, because everyone on the left gets offended and leaves. The only way you can make a website where the left feels "safe" is by censoring the right.
