I don't necessarily see where "customer consent" really enters the picture. Even if installing updates were optional, at some point you almost certainly want to install the updates, as it will contain bug fixes and enhancements in other areas of the product. This is much more a question of relying on "off-label" feature / bugs in a product, which will always be an issue. The problem here is that the advertised experience was "you can only use our content" and that should have been enough to scare off potential buyers from considering it as an option.
