The widespread use of QR codes appear to this writer, to be a backlash against corporate "branders" to jump on the WWW bandwagon to register and use WWW domains when they were first available in the mid-1990s.
In the name of "we're not going to make that mistake again," we now see these inane blots in inappropriate places, etc.
When malware distributors and crackers begin using QR codes to plant rootkits, worms, bots, keyloggers, and other little nasties in smart phones, which will likely spread to the networks in which they operate, perhaps the "me too" attitude regarding QRs will change to a more reasonable policy that balances risk against benefit.

Perhaps I misunderstand but I'm working under the assumption that BART's mandate is to provide public transportation, and any effort BART makes to assure continued service to the public would serve that mandate. In my experience, the court of public opinion is a ruse to lend legitimacy to mob mentality. More often than not, the mob tramples the civil rights of an innocent majority of bystanders. It follows that this kind of "protest" is an attempt by an interested few to disrupt the day-to-day activities of the indifferent many. BART seems to clearly understand their business.
