Planes can have multiple AoA sensors, and often do. An indicator which makes the pilot aware of divergent AoA sensor readings is a paid upgrade.

Though I also have to agree, as soon as this sensor's input became crucial to determining operational boundary conditions, the system needed some rather stringent hardening. It's a bit like leaving your auto-scaling load balancing infrastructure exposed and getting upset at your AWS bill the first time someone DDoS's it to inflate your hosting footprint.
