Maybe a Te user would take or leave the theory as it is, rather than try to refine it as a Ti user would.
The point is that this Te description is inaccurate in the first place. The only standard that Te users seem to be placing on the system is that it should match reality. I don't think that's too much to ask.
Yes, because Te wants to use it for a goal and if doesnt they cant. Ti on the other hand can mold the system and give and take and play with it as the its not a tool in the same sense as it is to Te.
Te wants a wrench to turn a nut, Ti says screw it, I can use pliers as long as while I turn it it does not slip. If you tell a Te to use pliers on a nut you better be prepared to hear why it wont work.
edit: now when you bring in Fi, Fi will say, I feel like pliers may work, so it goes against Te. Or a Te user brought donw to Fi, "this will frickin work, comon, squeeze harder, crap, stripped the head, where my drill(pliers go flying across room)" Now Ti will be "ok head is stripping, have nothing else, lets try until its stripped then grab a drill" :yim_rolling_on_the_
