All of these companies claiming that Apple is being unfair - turn the argument on it's head. So Apple are NOT allowed to create a piece of hardware that works with their platform and OS, just BECAUSE they own the platform and OS, in case that might give them an unfair advantage over others? That position would be incredibly unfair to Apple. Apple can invest huge amounts of money to create the phone and it's OS, but they're NOT allowed to leverage that to make other items, such as watches, headphones, glasses etc that work with the eco-system. Just because that might be unfair to someone else?
For example, do you see Bowers & Wilkins, Bose, Sony, Bang, or any of the myriad other headphone manufacturers whining? No. Because they compete on features and value for money. All Apple's wearable audio products feature incredibly easy pairing that other manufacturers cannot offer because that part of the system is closed to them. Unfair advantage to Apple? It's certainly an advantage. But it is most definitely not unfair. They built the damned system. But it's just a part of the functionality. There are plenty of other reasons for the consumer to favour, say, B&W over Beats, regardless of the nifty pairing. And so those companies still have a market.
If Tile focused on innovating and added features that might make people want to purchase their products, then they would do well. The U1 capabilities are not everything. Just a part of the tracking solution.
Stop whining Tile. Go do something positive and prove everyone on here that they're wrong, and that you do have a survivable business model.
