They already are. According to Geth and what we've seen so far, quite a few backers are flat-out demanding refunds from Giant Spacekat, which is what lit a fire under her ass in the first place and led to the hilarious chimp-out we saw previously. Hell,
one had the balls to leave one in the KS comments where everyone could see it. She already chimped, which means the backers
know she's paying attention to the revolt, which is a general indicator that they can and should keep fucking doing it.
Each backer that goes vocal is a tiny wound that fucking bleeds Wu's credibility as "GAME DEVELOPER BRIANNA WU," especially since as time goes on and she has less and less to show for it, she'll fade further and further from relevance. If she wants to salvage her career, she has to strike while the iron is hot, and with the backer revolt reaching her Patreon now as well, Wu can no longer afford to simply ignore it.
She'll try to pretend she's not worried.
She'll try to act like everything is fine.
In reality she's fucking panicking, as we saw from the last big chimping.
