Yes, the problem could have been made uninteresting by removing any
ambiguity. But as stated, it is very common (almost universal) to
speak of movement of a terrestrial object with respect to the surface
of the earth. If another frame of reference is intended, it is almost
always specified.

Very amusing.

According to you:

On the one hand, the problem is uninteresting if one removes the ambiguity
in the phrasing.

On the other hand, there is no ambiguity, because if a different frame of
reference were intended, "it is almost always specified".

So, the logical conclusion you arrive it in your post is that the problem is
uninteresting.

For an uninteresting problem, it sure generated a lot of traffic.
