I had my doubts that ethanol might be to blame but people running pure Gas have seen crickets come back. Crickets usually happen after the engine is warmed up and especially during idle, that marks ethanol off the list since it would chirp all the time if that were the cause.
I can tell you that cars have been required by law to run E10 since 1985. There's very little risk that Ethanol corrosion is the issue unless you want to call Subaru's engineering skill into question. Occasionally there have been issues with individual companies using out of spec parts but they're rare. Most likely the issues are gremlins from production such as the HPFP overheating.

e10 is not e85. You may be right. Or not. I have no idea and you don't either lol.
