EDIT: For anyone doubting the validity of a YouTube channel, Ellie Littlechild and Seán Ferrick are people that attend Trek events. I met Seán at STLV last year. On top of this they have interviewed Mulgrew. While this news is unconfirmed as Ellie stated, Seán relayed this information second hand from Star Trek: The Cruise, which featured the cast of Voyager for its 30th anniversary.
TrekCulture isn’t a misinfo outlet, so I would trust their reporting to be accurate.
That said, Mulgrew has made similar comments in the past.
I met Seán at STLV last year (I known I encountered Ellie but wasn’t aware till after the con) and was nice. There were people who asked for photos with him, which he seemed gracious to take. Me personally, I didn’t want to ask him because it looked like he was there with his partner.
They seem like good people. I think the site’s business model makes things look a little shallow or clickbaity, but they do good work.
I think these type of discussions came about shortly after season 1 of Picard.
