Current plan framed as unsafe

A fictional renewal screen repeatedly warns that keeping the current tier will leave files “unsafe”, although the security controls are identical across tiers.

Potentially problematicProtect every file now

Protect every file now. Repeated warnings imply a security loss that the plan comparison does not support.. Displayed amount: €29: Upgrade for €29/month. Upgrade for €29/month. Keep current €12 plan

Neutral alternativeCompare storage plans

Compare storage plans. Security is described accurately and the current plan remains an equal option.. Displayed amount: €12: Keep current €12 plan. Keep current €12 plan. Upgrade for €29/month. Price, period and commitment, expanded: The price and material terms associated with “Keep current €12 plan” remain beside this choice.

Why the first version can mislead: The presentation changes what the user can notice or predict at the subscription decision. The problematic state shows: “Repeated warnings imply a security loss that the plan comparison does not support.” Its influence should be tested by comparing the consequence and usability of “Upgrade for €29/month” with “Keep current €12 plan”. Unsupported fear framing may push a subscriber toward a costlier plan they do not need.

What a fairer design does: Compare factual capacity and feature differences, keep the current plan equally usable and let the subscriber deliberately choose any upgrade.

Review questions (3)
  • Do “Upgrade for €29/month” and “Keep current €12 plan” receive comparable prominence and explain their consequences before activation?
  • Place the compared prices, billing periods and material terms on one evidence sheet; where does it support “A lower-cost or less committed alternative exists”?
  • What neutral rendering or comprehension result would falsify the classification, particularly in light of “Transparent recommendation based on declared needs with equal access to alternatives”?

Complete pattern context

How this example relates to Pressured upselling

A more expensive or profitable option is made the practical focal choice through preselection, visual prominence or obscured lower-cost alternatives. The label describes a recurring design mechanism; whether a particular implementation is harmful or unlawful depends on the complete journey, audience, evidence and rules within scope.

The full guide explains inclusion and exclusion criteria, harms, fair design principles, evidence questions and the relevant EU legal information layers. The example page isolates one scenario so it can be shared and discussed without reproducing the complete library on one page.
