In cable's case the network quality is much better so there are many

you're also sharing that coax with your neighbours - and it carries all
the TV signals too[1]. Plus the cable operator needs to agree with each
modem what bands it gets so they don't conflict.

Also worth mentioning that the cable is only split to each household at
the street cabinets, whilst ADSL goes all the way back to the exchange.
