It is absolutely not straightforward and you are arguing a black-or-white fallacy.

As was discussed ad nauseum on HN before, in threads about "smart" vs "dumb" TVs, telling consumers to "not buy smart devices" is putting an disproportionate burden on them, given the market conditions as well as the actual consumer expectations and desires.

As ads are not required for the functioning of smart devices, compared to for example, electricity being required for a TV to work, or an internet connection being required for movie streaming to work, it is fallacious to suggest that consumers must avoid such smart devices to avoid unwanted behavior being forced upon them at a later date.
