We’re talking about creating a flow and perception that you can use a thing built around an assumption that you then intentionally change at some next step. It’s a breakdown of an implicit contract you create with the user, for the purposes of farming data, getting more signups, increasing conversions, or whatever else. It’s just dishonest.

A few years ago a family member contacted me about this very thing. They had found a nice looking website to accomplish a thing. The website had published pricing for packages of their service, and provided a “free” sample. Except after you spent all the time to get that free sample running, you couldn’t actually use it without paying.
