"While MSNBC may believe that I am worthless, I know better. I know who I am. I know why MHP Show is unique and valuable," Harris-Perry said. "I will not sell short myself or this show. I am not hungry for empty airtime. I care only about substantive, meaningful, and autonomous work.

"When we can do that, I will return  -- not a moment earlier."

After speculation about what the impact of  Harris-Perry's letter meant, MSNBC confirmed the cancellation "Melissa Harris-Perry" Sunday, according to The New York Times.

But viewers have expressed concerns that the cancellation of "Melissa Harris-Perry" diminishes the presence of diverse voices on the network.

The Washington Post reported that MSNBC President Phil Griffin said MSNBC is continuing to lead in diversity.

"We're in transition now, but that doesn't mean our commitment has changed," Griffin said. "We're rebuilding, but our principles are unwavering."

But Harris-Perry disagrees.

She tweeted articles that indicate her former network is decreasing diverse voices, including Miami-based José Díaz-Balart, who reportedly may be reassigned to another position so that MSNBC can expand "Morning Joe."

Harris-Perry also tweeted charts that seem to go against Griffin's statements.

But despite criticism, the former MSNBC host still expressed gratitude for her show

Harris-Perry's last tweet was a nod to what an executive reportedly said about her.

"She's a brilliant, intelligent but challenging and unpredictable personality." one executive told The Washington Post. "There was no plan to cancel her."

Harris-Perry has since added "have been known to be challenging and unpredictable" to her Twitter biography.
