Uber is known for being aggressive when it wants changes to the law -- just ask anyone who has received email after email asking for support. However, its latest effort might have crossed the line. The app-hailed transportation service is facing a class-action lawsuit over a text messaging campaign that called on Austin residents to vote for Proposition 1, which would let ridesharing companies operate without running fingerprint background checks. The lawsuit claims that Uber not only spammed Austinites with "vote for Prop 1" messages without their consent, but made it difficult to avoid those promos. Text replies went unanswered, and calling the source number would only give you an automated error message. In other words, it sounds like the sort of robodialer that would violate the Telephone Consumer Protection Act.
