From a personal perspective it doesn't really affect me because I choose what to put on my devices and what devices I choose enable me to do this.
Fines do nothing but put money in the government coffers to replace the tax these companies don't pay though it comes no where near.
Realistically and it won't happen because these companies fund governments but what should happen in that when they abuse their position they should be forced to implement the remedy immediately once it has been determined by a judge and failure to do so should result in a suspension of trading in the country. We have a big firewall, why can't it be used to block Google/Microsoft or Apple? If you were a monopoly would you risk that?
