Balancing, customer needs, limitation of hardware/infrastructure. Copper doesn’t handle symmetrical download and upload as well (this is where fiber comes in). There can be too much noise resulting in degraded consistency. Its prone to interference and leaks. To improve reliability, you get asymmetrical plans. Most people just want download. Which has historically been the cheaper choice. An example local to my area, a home plan will be 800 down and 20 up. A business plan will be 500 down and 300 up. The business plan costs more.
