That's Apple
Apple is a specialist in observing what works around its ecosystem, adopting the key functionalities into one of its own apps, and then throwing out the "copiers" because they're doing the same thing.
The only difference is that, this time apparently, they tried that on a company that has the money to take it to court, instead of some lone developer they could shit on without retaliation.
I'll be interested in reading about this case.
