They don't owe you anything for removing the news mix.
Not as a strict matter of their typical corporate disclaimer - but that's not the issue.
The issue is customer satisfaction and how the company chooses to treat their customers when an issue comes up.
To me, they seem totally tone-deaf and unresponsive in any meaningful way to the complaints that they are receiving and tone-deaf to the rationale given by customers for keeping the channel as simple good decision making (see posts in facebook threads).
It shouldn't matter if you have 20 million customers or whether there are other companies to switch to.
What matters is how a corporation treats EVERY customer as an individual - maybe that individual will have an idea worth consideration.
But with off-putting pre-digested pablum as a form letter, you're bound to create ill will and end up ruining your reputation in this instant media world - just look at facebook and the twitter feed for DTV customer service.
It just looks to me like corporate bullying when you don't announce or invite input in advance of this kind of decision making.
Sure, you don't have to legally, but is it in the best interest of the customer and the perception of the company as a corporate citizen?
