Presumably I would go find a catalog or a review site and read about the options, until I felt like I understood what was available well enough to make a choice. It's a push vs pull thing. I don't object to the existence of marketing material being made available for those who want to go looking for it, but to the preemptive intrusion of advertising into spaces where it hasn't been requested.
