Because of losing Uber? No.
Because they don't trust Apple not to remove other apps? Absolutely.
Consistency, stability and trust are quite important to maintaining a brand. Apple arbitrarily removing apps would definitely harm their brand image, especially as they're positioning themselves as a market leader in fighting for their customers privacy and trust at the moment.
But Apple would be required by users to give an explanation for those actions.
Still, all this post is kinda nonsense because it would never happen. It's more a karma bait lol
