The committee has voted on a legislative resolution to create a law that would require all companies to make the same type of charger, with one of the main reasons being to cut down on e-waste. Like we said, most, if not all companies with the exception of Apple already offer micro USB charging, so if anything this law is really aimed at Apple. It will take some time for this law to come into effect, assuming it is agreed upon by the Parliament.
Apple has their own reasons for using proprietary connections. This not only creates a sense of exclusivity, but can also prevent unauthorized accessories from being made (the Lightning connector has a chip that needs Apple’s permission to be used). At the same time designing their own connection allows Apple to decide how they want their device to be laid out internally, so it is unclear how much this will affect Apple if the law does come into effect.
