Whether they like it or not, shouldn't they ride safely and be considerate of pedestrians?

Anyway responsible cyclist ought to answer an emphatic 'yes', so I don't understand why stating it is a problem...

PS: and of course depending on the jurisdiction, including the UK where I am, cycling on the pavement is illegal unless there is an explicit notice to the contrary, in which case I would expect cyclists on pavements to really, really try to be invisible.
