Yeah, I wondered the same thing. Verification by company email reduces spam/noise, so I understand why it's done. Probably useful to have non-employees filtered out. But there's no way I'd trust the service enough to use it. Not to mention my latent fear of a data breach/leak ruining my career.
Aren't there any company mailing list addresses someone can provide? Someone inside uber needs to have some connections with IT - could be done easily I think. No email will be sent I am assuming? Or is there a verification step where one has to click on a link? Someone who has the app should verify.
