If Tilak Mandadi (LinkedIn profile not updated yet to reflect his Disney CIO/Parks position) did not actually orchestrate the restructuring himself (perhaps he was instructed from further up the executive chain), then he certainly did himself no favors by how he executed it (at least the announcement if not the actual restructuring logistics itself), oversaw the execution of it, and responded to it. If he's being muzzled by Disney from getting out in front of this story now with some spin control, then it is possible Disney has done so to keep him in their back pocket to throw under the bus if the legal and/or financial blow back from the story gets too hot.
So even if you see a "direct the termination of the executive responsible", it is entirely possible that the real architect(s) of the in-all-but-name layoff remain untouched, and you are only seeing the sacking of a scapegoat, even if they have a "CIO" in their title (he's CIO of a large division, but not over all of Disney). If instead something happened along the lines of Infosys, Tata Consultancy Services and HCL America (the contractors identified in the story) get their H1-B allotments catastrophically cut back (like 75-80%) with a maximum absolute cap set to the cut back level based on the 2014 allotment, for 7 years, then you would see very extreme avoidance of these kinds of restructurings in the future. Even if the H1-B program continues to exist, and even if American companies solicit for this kind of restructuring, there isn't a sales manager in the world who would allow that kind of deal through. Also effective would be to change the H1-B legislation so allotments become a granted privilege served at the pleasure of politics, not a protected right enjoying contractual legal protection, to nullify legal challenges to allotment changes, and let the executive (agency or President) or legislative branches alter the allotments by company. This would give the contracting companies a much greater incentive to solicit for more creatively value-added business, rather than extractive displacement-heavy business, as the political optics for any displacements (real or perceived) are just too much of a headache to deal with.
