Apple has taken ideas quite a bit. There's a term for it in the Mac world and in the iOS world they are infamous for "taking" tweaks done in the jailbreaking community. Rarely if ever is there any compensation or recognition given.

That's not right. Apple also many times doesn't not iterate as much as the independent developer would. But they do effectively kill off the small guy's work nonetheless.

That doesn't sit right with me.

Regarding ideas. People say that about so many things especially with features the big guys take. With hindsight it is done even more.
