They do keep them for some time. Think of how desktop motherboards still come with PS/2 ports even though 99% of mice and keyboards are USB. And with laptops, many new ones still come with a couple of USB A ports and an RJ-45.
However, as with everything in tech, some things have to get phased out at some point. From a manufacturer's standpoint it's probably 1) cost saving measures and 2) making space for new things (because you can't keep all the ports that have been there historically).
How is rj45 legacy? And why do the laptop manufacturers hate it so much?
It's not, but think of how many times it's used compared to the wireless.
