Lesson learned, obviously light "particles" do not behave like stones.

And if we take light to consist of particles and assume that these particles obey Newton's laws

No, don't do it again.

and we then expect light to be moving towards us with a speed that is offset by the speed of the distant emitter

It is not the case for light and also not for sound waves. If you make
the wrong assumption that light behaves like thrown stones then you
expect the wrong results.

"The Michelson-Morley experiment is fully compatible with an emission theory of light that contradicts the light postulate."

But the experiment it does not disprove the constant velocity of light.
It disproves that there is a medium in which the light propagates and to
which the velocity is counted. Like the medium of air for sound waves.
It was a surprise that there is no medium and that the velocity of light
does not depend on the direction of propagation.

"I introduced the principle of the constancy of the velocity of light, which I borrowed from H. A. Lorentz's theory of the stationary luminiferous ether.

Einstein left away the ether. This was the winning trick. The time
dilation and other relations directly following. And all those relations
have been proven later to a very high degree of accuracy in experiments
and in technology.
