I seem to remember a report saying that using ethanol could cause damage to the internal components of the engine. If true, why are they trying to bring it back? Have they fixed whatever was happening?

I believe the trouble was with various gaskets used at the time. The ethanol would attack the material and cause it to fail (swell and get soft). I think the automobile manufacturers have changed the gasket materials to withstand the chemical attack of the ethanol.

"Gasahol" from the 80's was gasoline with 10% alcohol.This low mix was compatible with the fuel pumps and seals but was very heat intolerant.Carberated vehicles would vapor lock and fuel foam when the temps got above 80.Fuel injection which ran at higher fuel pressures were immune to this problem because the higher pressure raised the boiling point of the fuel.So back in the day we had all kinds of driveability complaints in the summer.
