More hardware platforms that can be supported. The potential of a brand new OpenWrt/DDWRT like project for TVs is attractive, especially for Vizio TVs (which are extremely common and their factory software is terrible).
The context here is that (1) Linux allows proprietary drivers so even if they release all the code they're required to release it probably won't include drivers that TVs need and (2) code released by embedded vendors is very low quality so you'd have to spend years cleaning it up.
