The crickets are caused by a washer exposed to high pressure with too much tolerance. The most likely cause is heat. Mazda had some recalls recently due to HPFP overheating from seasonal variations in fuel.
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.

the fact of the matter is even beyond this filter, no one here knows for sure either way whether it'll effect any part of the fuel system long term. it makes sense to think it will. it's not like toyobaru has any incentive to lie and say it isn't compatible when it is.
these cars just haven't been out long enough for anyone to know anything positively. everyone with e85 in their tank is a guinea pig at this point.

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.
