TLDR:

The article suggests that Fox News fired Tucker Carlson due to his increasing influence and red-pilled perspective, which became a liability to the system operators who hold power, including Rupert Murdoch.

The decision was likely due to financial timing, as Fox Corp is set to take a big hit in Q2 earnings following a settlement with Dominion Systems. The article also notes that Fox Nation was struggling prior to Carlson's long show broadcasts, and that his firing has destroyed the digital brand. Carlson's views had expanded beyond media and social battles and into finance, economics, and politics, which was seen as a threat.

Ultimately, the article suggests that Carlson was removed due to his refusal to sell illusions and connect the dots of manipulation behind the false front of DC politics.
