If you're not in the UK and not using major services, yes, you don't have to care. The problem is basically that the major services will likely have to comply, because they do have a sizeable UK presence they'll want to maintain, hence they will introduce anti-features that basically ruin it for everyone. And if they do comply, it gives rope for the government to go after smaller players that don't. As a UK resident, I hope this will go the way of anti-piracy legislation - i.e. enforced against big services only while everyone else just continues to do whatever they want.
