If this gets implemented in a way that's clearly visible to the user, the effects on the CA are almost indistinguishable from the death sentence. The vast majority of customers would switch to some competitor that's not affected. Even a handful of saved customer support cases due to this warning is going to make up for the cost of switching. Most importantly, if users are confronted with warnings all the time, they become increasingly oblivious to them and might very well click through more important warnings down the line.
