I worked on the brazilian subsidiary of a (once) huge telecom vendor, I lost count of how many times I saw this happen.
YMMV, but in this case, It's all bureaucreacy. From the company standpoint was simpler to pay a third party to get the equipment away and provide a paper confirming they were properly scrapped and disposed. So the bureaucrats could happily scratch that passive out of the company inventory.
Most of that was surplus that was imported into the country but not sold. And I was not alone with that feeling. A colleague managed to build the one largest lab out of the headquarters, just by scavenging equipment about to be scrapped. Telecom switches, LAN switches, PBX, Cisco routers, Sun workstations, HP/Dell servers, we even had sales team conducting proof of concepts with customers, using those leftovers.
My last try was back in 2009, when the mother company was in Chapter 11 and we all knew what will be the outcome. I made an offer for a couple of racks of equipment by the time I was let go and was told that it is just too costly to manage "individual sells". One month later, the brazilian subsidiary closed down and, although the bankuptcy process is now done, nobody I talk to knows what happened to over 200 sq meter of equipment racks. Probably still in storage some place else.
