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

In addition to the good advice everyone else has given, I have had problems terminating CCA cable. I get the cable in the connector and crimp it with my (relatively cheap) crimping tool and it all looks great. Then I hook up the cable tester and it fails all of the tests so I cut the ends off (because they both look to be correct) and try again. I spent over an hour trying to terminate one cable a few months back. I thought it was the crimping tool at first. I had ordered some solid aluminum cable because I need PoE for an access point. When it came, every single cable I made with it terminated correctly first time. That was when I realized how bad the CCA was and tossed it in the trash.
