There's no way that Razor Wing and his allies would decieve Equestria and everypony should know and accept that. No matter what, I don't see Celestia letting ToV kill her friends and alies without some backup plan to screw the ToV over. Like only pretend to let the ToV have their genocide while authorizing Razor Wing and his allies to fight back and secretly giving them support.
There's no way Razor Wing would deceive Equestria, and everypony should know that? I disagree. Changelings lie to advance their own political agenda all the time; it's one of the staple points of their race. It's common knowledge that Razor Wing and Chrysalis are political rivals; it's completely within reason for ponies to believe that Razor Wing is pretending to be an ally of Equestria for the sake of strengthening his own position within the changeling realms. There's nothing unbelievable or unreasonable about ponies not believing Razor Wing is an honest ally. Is he actually genuine? Sure, he might be, but ponies have a lot of reasons to doubt that authenticity.
Either way, I think it should be worth noting, on this point, that the rebels don't actually really go after Razor Wing's forces; if you'll review the epilogue, you'll see that the genocide primarily takes place in the cities liberated from Chrysalis, with the rebels and other anti-changeling forces engaging in massacres of changelings after every successful liberation. There aren't any battles between the rebels and Razor Wing.
