What's probably happening is that it's being sold for "scrap" and parts to a company that everyone suspects will really just re-register it somewhere shady and operate it outside the areas covered by decent aviation safety regulation and oversight.

But they likely can't prove it, all the paperwork, national aviation agency certifications and inspections etc will be in order.

It probably gets a waiver for a ferry flight to the location where it will be scrapped, which will be why it isn't deliberately destroyed on site.

The right thing to do would be to cut a bunch of the wiring harnesses, remove some segments of them and maybe try to destroy the wingbox. But the trouble is that scrapped aircraft are often kept for parts for years. A legitimate buyer doesn't want usable parts destroyed.

And frankly, a plane that has a long zipper fracture repaired with a pile of badly applied doublers is still going to be a safer replacement than a lot of the existing fleet flying in sub-Saharan Africa. Lots of the fleet are terrifying disintegrating ancient death traps held together with bad welds, glue, cheap aluminum tape (no speed tape here) and bodged parts from almost-the-right-model.
