Please post your reference showing this. In college my roommate used to tell me that electric razors would tear your face off. Obviously he didn't have a reference for that claim.
I can field this.
E85 (85% Ethanol/15% petroleum gasoline) can damage the fuel systems of engines not engineered for this fuel. The alcohol will damage rubber/plastic components.
E85 capable vehicles have fuel systems with seals, gaskets, etc. rated for alcohol.

It depends upon the age of the vehicle and the components in the fuel system. I had all sorts of problems with my 1986 RV after taking a trip to Yellowstone and using corn gas. Rubber hoses disintegrated and all sorts of gunk filled up the fuel filter and jammed the fuel injectors.
The RV broke down 3 times on the way home and I took almost a $1,000 to repair the damage to a point where I could trust the RV on a trip again.
Corn gas should not be a problem on newer vehicles as this problem should have been addressed by using different materials. It would mean that my RV is useless however.
I guess that means I can sue someone. On second thought that would mean I need to speak to a lawyer and I'd rather have a plugged fuel system.
