By now it should be fairly obvious that Apple hates Facebook for a very good reason- Facebook is Apple’s single biggest threat. I’m completely convinced this has nothing to do with privacy or protecting users, it just makes for a convenient excuse.
If people slowly start replacing iMessage with WhatsApp or messenger, that creates a bridge to leave iOS for Android since Apple’s software is one of the main features of the phone. If you become less reliant on the software the hardware suddenly becomes a commodity.
This whole episode is giving me pause about staying in the iOS ecosystem. Beyond that I think some antitrust litigation is going to hit Apple soon.
