This has been explored in other threads previously, obviously there are commercial factors at play but Chargers are being removed also due to environmental reasons whilst there are arguments on just how big the impact is. Many consumers will not really need a charger and benefit from a more competitive price.
I realise removing SD cards slots is not universally popular but still possible to use an adapter and the focus nowadays is more on cloud storage. In a sense SD cards are older technology and some not a fan of them , whilst some consumers have encountered errors. see more here https://metimetech.com/is-removing-the-charger-from-the-mobile-really-ecological Hopefully Samsung and other companies will provide bigger internal storage in the future too .
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
