Earlier quoted context omitted.
I'm suspicious of any messaging system that has ties into rich media / embedded-in-chat content. I even wish I could disable URL previews, gifs, and inline images in Signal.
I didn't know it was possible to disable URL previews in iMessage[1] until I read this comment. Does toggling this setting only prevent the preview from displaying or does it prevent the fetch altogether? I wish there were a way to white list the URL previews for certain contacts rather than turning it off all or nothing. [1] https://discussions.apple.com/thread/7677834
