Operating system updates: from the date of end of placement on the market to at least 5 years after that date, manufacturers, importers or authorised representatives shall, if they provide security updates, corrective updates or functionality updates to an operating system, make such updates available at no cost for all units of a product model with the same operating system;

The only thing this quoted law stipulates is that you provide any updates, if you released them, for at least 5 years after the phone stopped selling. So this law is completely pointless.
