Jessie is hardly the first person to earn a GM card who doesn't shoot GM-level scores at majors, though. Nonetheless she's come under an unusual amount of scrutiny and criticism compared to those other (male, frequently unsponsored) GMs.
Even if you want to say she's the first girl ever to sandbag her way to GM -- and I've got no idea whether that's valid or not, it's just an assumption everyone is making -- she's still the first girl to do so. I'm pretty sure that's what the press release said. It didn't say she's now going to dominate the sport and beat all the boys.
Now, you can be upset that she gets the fame and the money, but I guarantee you that Jessie has generated more interest for her sponsors and more interest in USPSA -- among both males and females -- than 95% of the GMs out there. That's what she's paid for.
