Only works with their own products is lock-in.

Lock-out is Apple preventing third parties from making accessories that can match the first party ones in feature parity and seamlessness.

Apple Watch only working with iPhones=lock-in

No third party watch being allowed to use the same APIs the Apple Watch does or not being allowed to access iMessage, Apple Pay, etc = lock-out.

By locking their products "in", they're also locking third parties "out". How on earth would they be able to "lock-in" the Apple Watch to the iPhone while at the same time NOT "locking-out" third parties?

It's the same thing.

I have a apartement i rent out for vacation

If i offer to bring you fresh breakfast in the morning but not offer the service to other apartments down the street -> „lock in“

If i do not allow you to get your breakfast (of equal quality)elsewhere -> „lock out“

I think they're suggesting that lock in implies apple didn't write the code to help support 3rd parties. Lock out implies they actively wrote code to prevent 3rd parties.

With other companies there may be a difference. But with Apple, for all intents and purposes, it's the same thing. Because they are hostile to third-party integration using undocumented API's or interfaces.
