If it were really the cause of rod bearing problems or whatever, it would be FAR more widespread, and would affect other platforms as well. I personally believe the Mobil 1 myth was perpetuated by people looking for a scapegoat or something, and it just got out of hand. The vast vast vast majority of us really don't understand these oils on a chemical level, very very few people actually do, so for a bunch of armchair engineers arguing over the internet, it's pretty far fetched and I wouldn't give it much concern. There's been far too many Subarus run with Mobil 1 that have never had issues. The upset vocal minority will command the stage.

If it were a real issue, we'd be seeing the same trend with the FA, which actually shares nothing with the EJ series other than the flat four layout.
If it still concerns you, there's plenty of other options to put your paranoia at ease.

Really appreciate the feedback, I might actually start running Mobil1 now. I just bought Royal Purple. Lol so I might try it out next time if it goes on sale.
