Does this really matter? (Score 1)

I'm really not all that bothered if TfL get hold of information about where I'm travelling, as demonstrated by the fact I have an oystercard. What exactly would they do with it that would be so bad? However if I did care, all I'd have to do would be to buy my season ticket as a traditional magnetic stripe travelcard, which you can still do. There's no obligation to buy your ticket on an oystercard.
