Not quite "get off our lawn", yet clearly a sign post warning that the lawn might on day get a tad hostile if you choose to linger there without leave. Here it is, via Daring Fireball, Apple's latest Knowledge Base Article: iTunes: About unsupported third-party digital media players, aka the Palm Pre syncing saga:

This article is about iTunes and unsupported third-party digital media players.

Products Affected iTunes

Apple designs the hardware and software to provide seamless integration of the iPhone and iPod with iTunes, the iTunes Store, and tens of thousands of apps on the App Store. Apple is aware that some third-parties claim that their digital media players are able to sync with Apple software. However, Apple does not provide support for, or test for compatibility with, non-Apple digital media players and, because software changes over time, newer versions of Apple's iTunes software may no longer provide syncing functionality with non-Apple digital media players.

So, if/when iTunes breaks compatibility with the Palm Pre -- intentionally, incidentally, or otherwise, does this cover Apple?
