Apple isn't concerned about the people or the organisations themselves, but the content they make. You might disagree with it but Apple has been very consistent on this.
Apple is mostly concerned about social media apps having methods and process to handle inappropriate content:
"Apps with user-generated content present particular challenges, ranging from intellectual property infringement to anonymous bullying. To prevent abuse, apps with user-generated content or social networking services must include:
- A method for filtering objectionable material from being posted to the app
- A mechanism to report offensive content and timely responses to concerns
- The ability to block abusive users from the service
- Published contact information so users can easily reach you"
All of the above sounds pretty decent and normal to provide for a social network.
In addition, "Apps should not include content that is offensive, insensitive, upsetting, intended to disgust, in exceptionally poor taste, or just plain creepy."
Again all of this, or similar statements, has been in the guidelines since 2008/2009.
For some, it seems to have taken 14 years to discover Apple's rules.
