On Saturday, Dorsey posted a photo on Twitter with the caption "Boost @ChickfilA," showing he had saved 10% on a $31.58 order at the fast-food chain. A "boost" is a cashback reward Square users can earn when using a Cash Card, which is a debit card from the payment platform.
Critics immediately seized on Dorsey's support of Chick-fil-A — whose CEO has come under fire for his views on same-sex marriage in the past — during Pride Month.
"You must love the taste of bigotry!" one person wrote in response.
"Why is Twitter boosting a notoriously anti-gay company during #PrideMonth?" another indignant person wrote.
The backlash shows Chick-fil-A still has lingering problems with its brand image following remarks six years ago by the company's CEO, Dan Cathy, regarding his views on same-sex marriage.
Reports soon emerged detailing Chick-fil-A's many charitable donations to anti-LGBTQ organizations.
For months afterward, protesters rallied outside Chick-fil-A restaurants across the country and held "kiss-ins," where same-sex couples kissed in front of onlookers and TV cameras covering the backlash.
Jack Dorsey apologized on Sunday for eating at Chick-fil-A during Pride Month.
