The outcry began after Dorsey, 41, shared in a Twitter post that he received a 10 percent discount by making a payment through Chick-fil-A's app.
On Sunday, Soledad O'Brien, an American Journalist, anchor, and producer, called out Twitter CEO Jack Dorsey for promoting Chick-fil-A "during Pride month". Dorsey's meal - and his subsequent regret - has now fueled a flurry of tweets defending the chain and its values.
Dorsey was also attacked by Patreon engineer Erica Joy, who replied, "Please delete this or follow up with how much free advertising you're going to give GLAAD".
Chick-Fil-A is owned and operated by the Cathy family, which has expressed support for the biblical definition of marriage and donates to conservative Christian organizations.
A spokeswoman for Twitter pointed to Dorsey's response to O'Brien and declined to comment further. The chain's CEO Dan Cathy declared his opposition to same sex marriage in 2012 and since then it has been the focus of a backlash from a number of liberal groups. An email to Square and Chick-fil-A were not immediately returned. Victoria Brownworth asked: "Why is Twitter boosting a notoriously anti-gay company during Pride Month and an outspokenly Christian company during Ramadan?" Some also tweeted links to an article written by a campus gay rights activist about the "respectful, enduring communication and built trust" between he and Cathy in recent years and complained about the hyper-politicization of today's world. "The food is good", wrote one user.
