Grandfather when you take something back
When you raise prices, shrink a free tier or remove a feature, protect existing users: grandfather current terms for a period, give long notice, offer a choice (keep the old version for 90 days, opt in early) and tie the change to a clear gain. Taking back a freedom people already have triggers far more resistance than never granting it.
Plain label: notice, choice and grandfathering on removalsAlso known as: grandfathering, reactance, price change, feature removal, legacy plan
How it works
When a freedom people hold is restricted, they want it more and start attributing better qualities to it, a reaction called psychological reactance. Losing an established freedom provokes the strongest reaction, as when a county banned phosphate detergents and residents hoarded them and rated them better. Grandfathering, notice and choice shrink the felt loss, so the change is judged on its merits rather than as something taken away.
In the book. Restricting a freedom people hold raises their desire for it, and they start attributing better qualities to what was restricted (Ch.7, pp.184-189); gains followed by a sharp reversal provoke the most resistance (Ch.7, pp.193-196).

In a product [S]. Grandfathering, notice and choice whenever something is taken back.
Evidence Evidence grade B. Moderate evidence: solid studies with some limits.. Reactance is well established; product cases show the backlash when it is ignored (CASE-M12).
Evidence warning
Segment change metrics by users who had the freedom vs users who never had it (INF-K-48); averages hide the backlash.
What the research says
After a county banned phosphate detergents, residents smuggled and hoarded them and rated the banned detergents better on many qualities.

The book describes revolts that followed a period of improvement and then a sharp reversal, its model for why reversing granted gains is risky.

Before you start
- A planned price rise, plan change or feature removal that affects existing users
How to build it
- Web
- Keep current customers on their price for 12 months after a price rise, announce it 60 days ahead, and show the added value behind the new price.
- B2B
- Before removing a capability, consult the most affected accounts, offer a migration path and keep the old behavior available by opt-in for a quarter.
- Mobile
- Ship redesigns as opt-in at first and as the default only for newcomers, with a "switch back" option for existing users during a transition window.
What can go wrong
- Sudden paywalls on features people use.
- Cutting limits or earn rates for the median user without a compensating gain.
- Months of loose enforcement followed by a sudden crackdown.
Pairs well with
- Pairs with HK-MON03: price rises tied to added value.
- Pairs with in-t-sc-13: changes announced, never sprung.
