Yes it is, didn't Einstein say that gravity and acceleration are indistinguishable

[someguyihope]

"Zero-g" is different to "zero gravity". https://en.m.wikipedia.org/wiki/Weightlessness

The whole microgravity thing is pedantic, yes tidal forces exist, but at human scales they are not detectable.

In free-fall, the object is primarily being accelerated by gravity.

Yes but this is indistinguishable from the perspective of the falling object.
