Starting in January, Apple launched a series of C-Level discussions with tier-1 handset makers to underscore its growing displeasure at seeing its iPhone-related IP infringed. The lawsuit filed against HTC thus appears to be Apple’s way of putting a public, lawyered-up exclamation point on a series of blunt conversations that have been occurring behind closed doors.
Top-tier handset makers continued to avoid implementing multi-touch, but Apple could safely assume that they were hanging back to gauge Apple’s response to Motorola and HTC. If there wasn’t one, the OEMs would likely read the silence as a green light, especially after Google also moved to enable multi-touch on its Nexus One phone.
Even before the lawsuit, handset makers were having second thoughts about Google, which with the Nexus One had become a direct competitor. Now their faith in Android as the easiest and cheapest way to counter the iPhone has been shaken, says Reiner.
Seems pretty close to what I wrote here:
Therefore it’s entirely likely that HTC was singled out to disrupt the business logic of modular mobile software. HTC is the pioneer and the hub as the largest licensee for both WinMo/WinP and Android and the inspiration for hundreds of OEM/ODMs to make modular products.
… Other vendors looking at this licensing model might think harder about participating, and that may be the whole point.
