Interesting link but limited to only discussing rotational speed.If you want to know why rotation will slow, it's because you are moving mass away from the center of rotation.
If you want to see the actual math, there is a good analysis here: https://www.uwgb.edu/dutchs/PSEUDOSC/IceCaps.HTM
Let us assume he is relatively correct in his assessment.
What can we conclude about Axial tilt?
Or to use a classic example (just for fun):
Take a weighted spinning top and disperse the weight equally.
What happens to the spin of the top?
Possibly:
1/ It starts to wobble (excessively)
2/ it looses it's vertical orientation, "top can become bottom"
3/ Any axial tilt stability it may have had would be lost
3/ It fails to maintain spin for as long due to inherent wobble, due to inequities in it's balance, setting up energy using harmonics.
Then include a Moon in the system and ask again what happens to tidal forces and lunar orbit etc..
Hee hee maybe we will get to see the "dark side" of the moon from home...
maybe this video would help... then again maybe not..
