It's their choices to change, and/or reboot the history of Sonic if they want, and don't want to include the FF. If we force Sally and cie to be in, even "rewrited", it still be "forced", and no wanted by the comic. If they put them in the story, and gave them a good story, it great, but we don"t have to force that. If we do, and the gave us that, it's only fan services.
Still, even is they don't, Sally and cie will remain in the Fandom, for the better and the worst. So I'm ok with that decision, sorry.
