She's not too far off the mark. But she's confusing sole responsibility with sole custody, which obviously isn't good.
My life improved 10 fold the day I left all the Facebook groups. 
She's not wrong but her information is incomplete, which is what I told her. She also keeps screenshoting the guidelines from gov.uk, i said to her there is 3 ways on the guidelines though you only keep speaking of 2. Other individuals just have Facebook to rely on and you need to start updating the information that you give out. She basically said Facebook should be a starting point.
Maintenance and shared custody is not the devil. You can get visas for your dependents. You just need the documents to prove it.
