Breh if you really are close to this industry then you know how it really works. Wind Sun Sky a canadian company are doing the keyframes and sending them more than likely to Korea or the Philippines and animators from both those countries are making well over the country average. Its not 1990 anymore the industry has come far in providing wages for animators. Nobody is getting abused and if they are they made that decision. Artists will always get taken advantage of, it’s the exact reason why I and so many other left the animation industry.
In this era they is really no excuse for the shyt quality of invincible other than poor planning or poor budgeting for an animation that takes 2 years to come out.
