I don't think people think through to the end enough. Lidar can't be tricked as easily. If Tesla were to attract a group of malicious actors that hated Tesla I wouldn't put it past those actors to figure out ways to confuse Tesla's non-lidar self driving to make it frustrating to Tesla owners but more specifically to cause financial impact on a self driving taxi fleet that wouldn't be possible with Lidar.

Has Tesla accounted for malicious actors trying to sabotage it's vision choice and not just plain jane driving scenarios?

I think at scale and once rolled out malicious actors are going to be one of the number one economic impacts of self driving taxi economics.
