Apple Maps: In what respect is this "stolen"? By the same argument did Google steal from Garmin or MapArt who in turn stole from cartographers? Not sure what you're saying here. Mapping applications have been around for decades. Apple needed one on their phone. They made one. It's similar to other mapping apps, Google's included, but also took a new approach in some regards.
Apple Watch: It's a smart watch, they didn't invent the category, but it's a novel form-factor, instantly recognizable. The operating system is also highly distinct from others. You'd never confuse an Apple Watch for anything but an Apple Watch. Some of the Android based ones are going out of their way to look like non-smart watches. At least Motorola has their own design language here.
F.lux: Significant functional overlap but these sorts of tools have been around since the 1990s. It's not like F.lux invented this, they just popularized it. Maybe it was a dick move on Apple's part, or maybe it was just a thing they thought should be core to their product.
When Microsoft wanted to add faxing functionality to Windows they could have bought WinFax, but they instead made their own thing. Is this stealing?
I think your definition of stealing and copying is extremely loose, to the point where the term has lost all meaning.
Your comments use words similar to mine like "the" and "a". Are you stealing my words?
