AT - you are being pedantic to defend your incorrect answer
No, you are defending your meaningless answer. As JesseM says:
it's pretty meaningless to talk about coordinate acceleration in general relativity without specifying a choice of coordinate system
you are the one who arbitrarily assumed a specific category of acceleration.
Well you assumed two things arbitrarily:
1) specific category of acceleration : coordiante acceleration
2) specific frame of reference where the coordiante acceleration is not zero
the "general" definition of acceleration is exactly as i stated, and includes changes in direction.
Not in General Relativity. As DaleSpam already stated:
Traditionally the unspecified word "acceleration" is understood to refer to "proper acceleration" by default.
And the original question was even specifically about the acceleration experienced by the object. This term usually refers to absolute proper quantities like proper time, which is the time experienced by the object.
