Not really fair? Sure thats your opinion I guess.

There are only 3 SBC engines that use forged cranks in the last 30 years.
1) 662hp/LS9(forged steel crank/forged pistons/forged titanium rods),
2)556hp Cadillac 6.2L LSA(forged steel crank/cast hyper pistons/forged PM rods,,
3)505 hp 7.0L LS7 forged 4140 steel crank/cast hyper pistons/forged steel titanium rods.

Using your logic, all aftermarket manufacturers that produce a cast crank will experience breakage, simply because it is made of metal that is cast in a casting, vs. being forged into shape?

I could have posted pages of issues with Eagle cranks.

Look at the 4340 forged unit, it was out 1-2 thou. from center to edge of the main bearing surface. Thats horrible, but typical of many products manufactured these days.
