You are confusing frames of reference, as used in GR, with reality.
He also says in the same paper that the g-field is caused and determined by the energy tensor of matter...he doesn't say that an accelerating earth causes the g-field.
I will add to this with another quote from Einstein. You'll need to read the first part of the paper to get the the context, but the point he makes here is important.

I must warn the reader against a misconception suggested by these considerations. A gravitational field exists for the man in the chest, despite the fact that there was no such field for the co-ordinate system first chosen. We might also think that, regardless of the kind of gravitational field which may be present, we could always choose another reference body such that no gravitational field exists with reference to it. This is by no means true for all gravitational fields, but only for those of a quite special form. It is, for instance, impossible to choose a body of reference such that, as judged from it, the gravitational field of the earth (in its entirety) vanishes.

The wiki implies that an accelerating earth is the only logical explanation for the equality of gravitational and inertial mass. It is misleading to use so heavily the work and reasoning of Einstein , when he came up with an entirely different explanation.
