But, the parties involved told Business Insider the outrage has nothing to do with their decisions to end their professional relationships with the Instagram famous comedian.
Things got bad for Ostrovsky after The Hollywood Reporter broke the news last week that he had signed with entertainment agency CAA "for representation in all areas."
That set off a wave of accusations from Ostrovsky's internet and comedy colleagues claiming that he had been plagiarizing his jokes for years.
The outrage grew so loud that THR decided to update its story with an open letter comedian Davon Magwood wrote about Ostrovsky earlier this month. In the letter, Magwood accused Ostrovsky of posting his joke without attribution. In fact, Ostrovsky is known for "aggregating" jokes and sharing them on his Instagram account without credit. Ostrovsky later gave Magwood his credit.
Among Ostrovsky's many detractors is actor and comedian Patton Oswalt, who posted and retweeted several tweets directed to the comedian.
My favorite Jane's Addiction song is "Been Caught Aggregating."

Always chokes me up in "Purple Rain" when Prince sings, "Baby I could never aggregate you from another..."
