Sony should not be permitted to disable advertised features that no doubt played a part in buyers' choices;it is perfectly acceptable for Sony to stop selling new units that no longer have those features ,and which are not advertised as having those features.
Sony demanding the right to disable advertised features of any product in order to continue using services or functions the users have been promised and have been using is just wrong.
And as much as people love to bash MS,if MS can bring the best product for the market at the best price then MS deserves to win.
I do believe honest competition is good and would hate to see a world where there is only one console,one car company,one language,etc.
