There's only a limited amount of space in the airwaves. Either old stuff gets turned off, or you can't add any new stuff. I agree that mandatory obsolescence is a bad thing, but the first 4G networks went online in 2009 and are now 15 years old. Dropping support for >10-year-old handsets isn't great, but definitely understandable. If you're mad at anyone, it should be the companies who keep selling 3G-only handsets until this very day.
