Integrated browsers really bug me and I wish Apple would update their TOS to require launching Safari (or better the user's choice) The problem with integrated browsers is the AFAICT the app doing the integration can read everything that goes through it. That means if you click link and it links to page that asks you to login the app hosting the integrated browser can read the keys/input/network traffic. How can I trust any such app not to be spying on me? Sure I have to trust Apple with Safari or Google with Chrome or Mozilla with Facebook but that's 3 companies to trust, not one company per app * every 3rd party library they integrated. At maybe a more minor level it also means the hosting app can read every URL you visit from linked pages.
