I received some private feedback. I think you're already convinced but I'd still like the record the information here in case anyone else asks. I'll summarize as pros and cons.
Pros:
- Push notifications for Tapatalk users
- Might gain more members who only use Tapatalk for visiting forums
Cons:
- Past mistakes including hijacking attachments (storing on their servers instead of the forum)
- "Spam" I'm seeing so many reports I can't get it straight. My best guess is they're injecting their own ads all over forum pages to Tapatalk users.
They want to make money too. It probably comes at the cost of user experience. There are trust issues with what they can do with forum content.
