\"Hopefully,\" Wieber said, \"we're shifting away from the culture of prioritizing medals and money and the success of the athletes over the health of the athlete,\" which is something she's been working on herself as head coach for the University of Arkansas. She said she sees Biles as a \"pioneer\" and that makes her \"really proud.\"

Moceanu, who won gold as part of the U.S. team in Atlanta, told ABC News in a written comment that Biles was \"finding new ways to be heroic,\" saying she was \"actually very proud of Simone.\"

\"What she did was actually very brave and is a positive sign for the future of the sport,\" Moceanu wrote.

Biles has said she remained in the sport in part to be a leader and continue to push to change the culture.

Nastia Liukin, who won gold in the individual all-around for the U.S. at the 2008 Olympics, wrote on Instagram about Biles, \"Thank you for creating a safer space for current and future athletes to unequivocally be themselves.\"

\"I think gymnastics has had no choice over the past couple of years than to change,\" said Wieber, who won team Olympic gold in 2012. \"And a lot of coaches are being pushed to look at, you know, what their own coaching style is and look at how it is affecting their athletes long term and make some adjustments.\"

But there's still a ways to go both culturally and in examining what USAG did or didn't do about abuse by Nassar and others, added Wieber, who was abused by Nassar and coached by John Geddert, who killed himself earlier this year after being charged with human trafficking and sexual assault.

Noting that no one knows what Biles, who was also abused by Nassar, is going through at the Olympics but herself, Wieber said of competing for USAG, \"I can take some guesses and imagine that it's probably difficult to represent an organization like USA Gymnastics for her, an organization that has failed her so many times and failed a lot of us.\"

She continued, \"I'm just making assumptions here, but I can imagine that it, it adds to the weight of what she carries with her every day of having to represent that organization.\"
