Raleigh-based Lulu, a global provider of self-publishing services, is the latest tech firm to join the protests against North Carolina’s HB2. Meanwhile, 170 startups and emerging firms have now signed a petition formally protesting the bill.

Lulu joins other high-profile tech firms such as Red Hat and Cisco as well as life science giant Quintiles to speak out against the Public Facilities Privacy & Security Act, commonly known as House Bill 2.

The bill requires people to use public bathrooms that correspond to their birth gender, excludes gay and transgender people from protections against employment and public accommodations discrimination and blocks cities and counties from extending such protections to them.

LGBT advocacy group Human Rights Campaign filed a public records request Thursday to determine what role, if any, religious conservative groups played in drafting the law. Meanwhile, supporters of the law say the group is misrepresenting it, WRAL News reported Thursday.

HB2 “stands in direct conflict of the work we do every day to give our authors a voice, to enable their success, and to create a more empowered and tolerant society,” Lulu said in a statement. The company was founded by Red Hat co-founder Bob Young.

“Lulu stands for being remarkable. We strive every day to make the world a better place by allowing authors to tell their stories through the free flow of information for the benefit of humanity,” the statement provided by Erika Brooks, vice president of marketing, said.

“We accomplish this through an inclusive, transparent platform that gives every author –the single parent, the politician, the poet, the entrepreneur, the priest, and the scientist – the opportunity to be heard equally without censorship or bias. We do not make judgments on our authors’ works, nor discriminate based on their content.

“These values are at the foundation of our company, and HB2, which was passed in our home state of North Carolina on March 23, stands in direct conflict of the work we do every day to give our authors a voice, to enable their success, and to create a more empowered and tolerant society. As a business, we cannot support any legislative decisions that encourage, promote, or facilitate actions that clearly oppose and oppress our corporate values by marginalizing and degrading people and their stories.”

Meanwhile, the startups against HB2, an effort organized by executives at several Triangle emerging companies, said 170 firms have now signed its petition. Its website also now includes anti-HB2 statements from more than 200 executives.

“HB2 is having disastrous short-term effects that will negatively impact the state long-term,” said Christopher Gergen, a founding partner of HQ Raleigh and an organizer of the effort.

For example, PayPal has decided not to bring 300 jobs to Charlotte and Deutsche Bank froze an expansion in Cary. Meanwhile, Benefit Corporation is moving a B Corps Champions Retreat from N.C.

“While [Gov. Pat McCrory] is taking some steps to pull back, his actions don’t go far enough,” Gergen said “This solidarity with startups will help catalyze a conversation at the statewide level, which we hope will lead to a repeal and get our state back on track.”
