Do you know the term “trust thermocline”?

Basically it described a problem with the boiling the frog technique. There’s a point for every user at which they’re fed up with the bullshit, lose all trust in you(r company) and are hard to impossible to get back as a customer. Every customer leaving has a little unnoticeable effect on you, but with time there will be so many people that you lost that all your tactics to lock your users in will fail.
