Why do people hate Copper Clad Aluminum Ethernet Cables for PoE cameras? (alien.top)

On the Reolinkcam subreddit they are big on if you are wiring your house internally with ethernet cable do not use Copper Clad Aluminum cable only full copper cabling?

Why is this?

Does it make that much of a difference?

Genuinely curious to know as locally for me the cost is quite high for full copper cabling

One additional negative (to the already numerous comments against CCA) is the general frailty of the cable itself.

It is fairly easy to break one of the conductors inside the cable, if it gets kinked/snagged while pulling the cable. Copper is much more forgiving.

Also, for those who foolishly crimped plugs onto the ends of the cables, they probably learned fairly quickly that the terminations failed at a higher than normal rate compared to copper cables. I suspect that the aluminum, being more brittle than copper, is probably cracking inside the connector either during the crimping process, or due to strain on the cable at the connector.
