There are reasons for Charter officials to be sensitive. Mr. Cuomo’s administration has threatened the company’s very existence in New York: The governor’s appointees at the State Public Service Commission, which oversees the telecom sector, voted at a hastily convened meeting in late July to force Charter to sell its operations in the state.

Those who have tracked the Public Service Commission said its drastic step to revoke Charter’s merger with Time Warner in 2016 was extraordinarily unusual. It came in a special session called with less than 24 hours notice, while one of the commission’s most vocal members had told colleagues she would be out of town on vacation.

“I can’t speak as to why they would have a special session without me but it is for the chair to determine why a special session was called,” said Commissioner Diane X. Burman. She had missed one previous regular session in her five years on the commission, she noted, when she was in the hospital. She declined to speculate about her colleagues’ motivations.

Without her, the meeting lasted less than 20 minutes and none of the three commissioners who attended asked any questions before voting to pull approval of Charter’s merger.

A commission spokesman, James Denn, did not return calls for comment and declined to answer specific questions about whether the governor’s office was involved in their decision. He said in a statement that the commission “appropriately moved forward to promptly protect the interests of New Yorkers.”

Marcus Molinaro, the Republican candidate for governor, said on Friday that he believes Mr. Cuomo “put his thumb on the scale of a major P.S.C. decision” because of “his rage at NY1 News.”

“I think Andrew Cuomo got furious with NY1 News and effectively pulled the plug on an entire cable system as punishment to NY1, and as a warning to others he can affect who dare ask him tough questions,” Mr. Molinaro said.
