My device (Galaxy Nexus on Verizon) has no warranty - I bought it used on eBay. Considering that Google has (quite arbitrarily) decided that the Galaxy Nexus does not merit the KitKat treatment, I think it is both petty and disingenuous to evict the Cyanogenmod installer off the Play store because it “will” void my warranty.
Furthermore, Google Play store differentiates which downloads are permitted by device - not all apps are available for all O/S versions or devices (a major pain point for Android developers) - so they could quite easily still permit the Cyanogenmod installer for devices that are clearly too old to still be under warranty.
