I suppose one of the differences is that it's a "feature" announced from the start and you don't have to purchase a kindle fire if you don't want one, where as it's pretty hard to not go to the internet via bt wholesale.
Also the whole phorm thing was done in secret and was very underhand, if they'd gone "we're going to do this, you can opt out here if you like" instead of turning it on for x number of folks and not telling anybody, there'd probably have been far less outcry.
