As I've said before, the ball in contact with the Earth is constantly decelerating (with respect to the Earth) because aether is always imparting movement (with respect to the Earth, again).

Are you claiming that, in the DET, a ball sitting stationary relative to the Earth (just sitting there), is also in fact decreasing its velocity relative to the Earth at the same time?
Is a ball sitting on the surface of the Earth stationary relative to the Earth?
Is it changing its motion relative to the Earth?

Once again, every object exists at a point in space. When space moves (with respect to a fixed point) the object's default state is movement with respect to it: if something impedes that motion, then it must decelerate the object. However, said object always exists at a point in space, and so always has motion imparted by space: and so it must be decelerating every second if it is to remain stationary with respect to the reference point. An object does not change its motion relative to the Earth because the Earth is decelerating it and preventing its motion.

That is not in accordance with Newton's Laws. The explanation given in your previous posts make it clear that relative Newtonian and Galilean motion does not work the same way as has been observed on the macro-scale nature. Thank you for having adequately clarified my question regarding the DET. I feel quite comfortable in my understanding of it.

It is perfectly in accordance with Newton's laws, so long as you accept that aether is not some literal, material, mass-possessing object: it is the points in space that objects occupy. Something may move with respect to the Earth while being fixed with respect to aether (as is the case generally), the only aspect that is odd with respect to classical applications of Newtonian mechanics stem from the fact said mechanics aren't typically meant to model the flow of space. After all, where would mass enter into it? Newtonian mechanics hold, so long as they are applied where they're defined to apply. No one would seek to apply Newton's first law to, say, kempe chains: the idea is absurd, there is no common ground whatsoever between the two. One is hardly relevant to the other. That doesn't mean something's 'not in accordance' with Newton's laws, only that Newton's laws aren't meant to describe every conceivable entity. Indeed, trying to apply them to aether is clearly impossible. What is a force applied to space?
Think of it in terms of the initial instant of contact, as I'd hope we're agreed on that situation. When an object collides with the Earth's surface, and due to the force of contact has its velocity slowed to zero with respect to the Earth, then there is an upwards force from the Earth. If the Earth were removed at that instant, the object would in fact continue to fall. The only thing to grasp, under DET, is that the coordinates of an object may shift with respect to the Earth. No force is required to shift massless coordinates: but to alter the velocity of an object, a force is required at every instant.

"No force is required to shift massless coordinates: but to alter the velocity of an object, a force is required at every instant."
That is it right there. Constant forces are not required to alter velocity. The Earth needs a moment of exerted force to alter the velocity of a ball (it is given for the hypothetical here a ball stationary with respect to the Aether). The ball's velocity, which was zero relative to the Earth, on contact with the Earth will experience a force altering its force so its velocity becomes equal to that of Earth's relative to the Aether. The ball need only be accelerated to the velocity of Earth in the Aether-based reference frame. Because there is no downward force from the movement of Aether, the force of the Earth need only be applied once to the ball.

Constant velocities are not needed to alter velocity when said objects aren't constantly being made to move with a certain velocity. I've said this multiple times: this is the effect of aether.
