To be honest, there can actually be good reasons to destroy equipment instead of letting people rummage and get what they want, especially in bigger companies
The main reason is that, in order to be able to write off the value of the devices (and be able to use that to offset gains somewhere else in the business), a company needs a receipt from an approved recycler/disposer.
Secondary reason is that the devices might be old enough to have leaded solder, and without actual proof that those devices were properly disposed of, a company might be liable (like a company that dumps solvents on a drain to avoid costs)
Also, probably not as much a concern for measurement devices as computers, confidential data on devices might require a disposal company to certify that everything has been erased properly
When I was working for one of the biggest software multinationals, the computers/laptops that were too old to be used daily, had to be disposed of thru the proper channels and if anyone wanted to buy back their laptop/PC, they had to go thru that third party which would ensure everything was properly scrubbed from the HD and any damaged equipment recycled according to environmental rules (which offered special deals for employees, but still charged a lot more than the "free" you could get if you simply took it home.Incidentally, simply taking home your old laptop without properly disposing of, could be considered ground for dismissal)
And, yes, wasteful and bad for the planet, but it makes sense from a legal liability and tax optimization point of view
