The algorithm has changed to adjust the fyp to include everyone from teenagers to grandparents and it limits the content of people who had a specific niche and limits their ability to get on others fyp. It was better the way it was before these changes. It also opens the door for underage users to see content that is not appropriate. It also tends to promote verified users only and limits the growth of non verified users. This was a terrible change and opens the door for other apps to thrive.
