Short answer: Data cables such as network and telephone cable contain thin copper conductors inside a lot of insulation, so the copper yield is low and stripping is slow, which means they are only worth collecting in large quantities from an office or building clear-out and are usually sold insulated, and some cheaper cables use copper-clad aluminium rather than solid copper.

The conductors are thin, and the insulation and jacket make up most of the weight.
Check the conductor
Cheaper cables may use copper-clad aluminium, which is worth far less than solid copper.
Bulk only
A building’s worth of cabling can add up, but a few leads rarely justify the effort.
