You made 4 points about things that may or may not happen. For some of them you made the worst assumption possible (eg: batteries may not be available to buy. As if China won’t go brrrrrr making them :P ). And that’s why I said that “I guess” that for you the glass is half empty (aka you’re focusing mainly on possible issues).

You might be right of course, but keep in mind that the main players (eg: Samsung, Apple) already sell some components to 3rd parties or are starting to do so. Even Apple, with all their control, don’t disable 3rd party batteries on their phones, they just show you a warning inside the settings menu. So, from a slightly different point of view, the glass is actually half full and you may not need additional rules. I guess we’ll have to wait and see if someone wants to piss off the EU and have more rules imposed on them.

Anyway, it was a quick reply to the top comment on this thread (when I opened it at least). I didn’t spend much time trying interpret your comment :P
