Apple has faced criticism for its restrictive policies that limit the capabilities of non-Apple devices, particularly smartwatches like Pebble, when used with iPhones. User concerns center around the security implications of allowing messages to be shared with untrusted hardware via Bluetooth, suggesting that this introduces significant risks. Additionally, there are complaints about Apple favoring its own services and devices over third-party options, raising antitrust concerns. The frustration among users also highlights a desire for greater interoperability among devices and emphasizes a lack of trust in Apple's motives, which are perceived as monopolistic. The conversation also touches on how Apple's ecosystem can hinder user experience and innovation for wearables.
