Girlfriend posting her baby daddy/ex

I'm gay and have a girlfriend who is also gay. She does have a child from when she used to date men. To explain why this is such a big deal I have to give her backstory.

Her boyfriend was 18 and she was 23 when they got together. A little age gappy but legal. She had his baby when he was 19 and she was 24 and they did content creation on YouTube. They don't do that anymore and actually deleted their couples channel. Things fell apart when they broke up. She did something very sneaky and I'll admit I don't agree with it. I understand what she says when she claims she wanted to protect herself Incase she became a single mom but I feel there were ways to go about it. She was already a college graduate when they started dating and he was still in Highschool. She graduated in accounting. He didn't come from a lot of money and had some learning disabilities and didn't really know much about finances. What she did was put everything in her name. Including taxes. She admitted she kind of used his ignorance to her advantage. He didn't even have a bank account. He had cashapp and she cash apped him money. So when they broke up, not only did he not have anything or own anything, for the 5 years that they were together he had no record of ever having income even though he was the one editing the videos and doing the content creation along with her. I understand women wanting to protect themselves Incase something happens. I just can't agree with leaving someone with nothing when they contributed equally to the work. And she does admit it was wrong if her to do that. I'm a strong believer in people can change. Her and her ex don't even talk. They have to talk through a third party and only see each other at pick up and drop off. She recently decided she wanted to content create again on YouTube and i thought that was cool! But she has been reuploading old videos of them from their old YouTube channel. That bothers me. You have a girlfriend and are uploading videos of you and your ex as a couple? Not to mention she got a warning from his lawyers that she can't upload videos that have him in them. He doesn't want her profiting off of him. She's gonna continue because she said she owns them and can do what she wants. I told her why can't we make TikToks together. Why does she have to reupload videos of her and her ex and she said she's hoping to gain back some of her old following. Would you be okay with this?
