"I know the decision we made was very hurtful to LGBTQ community," Wojcicki said, speaking at Code Conference. "That was not our intention at all."
At the same time, Wojcicki said she was involved with and agreed with the company's actions in the case.
YouTube initially said there was no violation of policy before deciding a day later to suspend him from the program that allows content creators to get advertising revenue from YouTube.
Her comments at Code Conference follow both fresh scandals as well as a series of new policy changes aimed at limiting the availability and spread of hate speech and so-called "borderline content."
"This is something we had been working on for months," she said, saying it involved hundreds of people at the company.
The bigger picture: Asked by Vox's Peter Kafka whether YouTube can ever get a handle on the content issues it faces. Wojcicki said the company can continue to get better, pointing to progress the company made on violent extremist content. "I see how much improvement we have already made," she said, adding later: "I'm not saying we're done."
Wojcicki rejected the idea that people should have to get approval before posting videos.
"I think we would lose a lot of voices," she said, adding that there should be "tiers" of trust, requiring a track record for having ads or live streaming.
As for whether YouTube has contributed to the radicalization of the right, Wojcicki declined to answer directly. "Our view is we are offering a diverse set of content to users," she said.
