There have been murmurs that Samsung would follow in Apple's footsteps by taking out the charger in its upcoming flagship. The company seems to indirectly acknowledge this by deleting a Facebook post it had up that made fun of Apple's decision to take out the charge in the iPhone 12 series. You can see a screenshot of the post above. It went live the day Apple announced the new iPhones.
Apple attributes the decision to help reduce its e-waste. And it can certainly be helpful if other OEMs follow suit. Apple still includes a USB-C to Lightning cable in the box, so we could hope that Samsung will keep a USB-C to USB-C cable in the Galaxy S21 series.
