Industry reaction after rooting your Android

Until the early 2010s, the response of tablet
and smartphone manufacturers and mobile
carriers had typically been unsupportive of
third-party firmware development.
Manufacturers had expressed concern about
improper functioning of devices running
unofficial software [11] and related support
costs. Moreover, firmware such as
CyanogenMod sometimes offers features for
which carriers would otherwise charge a
premium, such as tethering. As a result,
technical obstacles such as locked
bootloaders and restricted access to root
permissions have commonly been introduced
in many devices. For example, in late
December 2011, Barnes & Noble and
Amazon.com, Inc. began pushing automatic,
over-the-air firmware updates, 1.4.1 to Nook
Tablets and 6.2.1 to Kindle Fires, that
removed users' ability to gain root access to
the devices. The Nook Tablet 1.4.1 update
also removed users' ability to sideload apps
from sources other than the official Barnes &
Noble app store (without modding).[12][13]
However, as community-developed software
began to grow popular in the late 2009 to
early 2010, [14][15] and following a statement
by the Copyright Office and Librarian of
Congress (US) allowing the use of
"jailbreaking" mobile devices, [16]
manufacturers and carriers have softened
their position regarding CyanogenMod and
other unofficial firmware distributions, with
some, including HTC , [17] Samsung , [18]
Motorola [19] and Sony Ericsson , [20] even
actively providing support and encouraging
development. In 2011, the need to
circumvent hardware restrictions to install
unofficial firmware lessened as an increasing
number of devices shipped with unlocked or
unlockable bootloaders , similar to the Nexus
series of phones. Device manufacturer HTC
has announced that it would support
aftermarket software developers by making
the bootloaders of all new devices
unlockable. [11] However, carriers such as
Verizon Wireless and more recently AT&T
have continuously blocked OEM's such as HTC
or Motorola from releasing retail devices with
unlocked bootloaders, opting instead for
"developer edition" devices which are only
sold un- subsidized, off contract. Similar in
practice to Nexus devices, but for a premium
and with no contract discount
