Since the 4/3 sensor gathers so much less light than FF at the same f-stop, how many stops should I overexpose by on a FF body if I plan to crop in post?

On any format, when shooting in raw, you should expose to get the most light on the sensor consistent with desired DOF and lack of motion blur, so long as you don't blow out highlights in which you wish to preserve detail.

Since the 35-100/2.8 is so clearly different in dof from the 70-200/2.8, why not compare it to the 24-70/2.8, which is a similar range of focal lengths and therefore has similar dof?

Because it's more useful to compare equipment that produces a comparable result. In this case, you'd want pictures taken from the same position with the same angle of view producing the same DOF with similar noise.

The 35-100 and the 24-70 will result in much different angles of view (35 compared to 24, 100 compared to 70 and intermediate values).

The only problem is you can buy FF, and cheap out on lenses, to approximately match m4/3s IQ (but not size and weight), or you can spend big and gain the IQ. You can't have it both ways though, well, not without spending really big.

Of course, if you do go the FF cheap lens route, then you lose out on weather sealing, size and other useful stuff.

Also, just a point, but you're comparing a weathersealed stabilised lens, with a non weathersealed, non stabilised lens. Over here, at least the Canon 70-200 f4 IS costs more than the Panasonic.

The Canon L USM lenses are regarded as high end lenses with high IQ. The 70-200/4 is an L USM lens.

The thread is about the E-M5, which has in body stabilization. In lens stabilization doesn't matter for the E-M5.

The claim was that the Canon equivalent cost 4x as much.

Ah ok. Didn't realise it was weathersealed.

It should have IS though, unless you're happy comparing one system with IS, with one without.

And I don't think I've seen anyone claim 4x higher cost. You're argument is about the fact that they described it as equivalent.
