Ask HN: When does changing pricing models break user trust?

Changing the deal retroactively breaks trust. Sustainable monetization is fine — but only when new costs map to new value. Taking away features people already paid for isn’t pricing evolution, it’s expectation debt coming due.

My rule: You can change the future. You can’t rewrite the past.

If you want to monetize long-term, protect ownership, data access, and core functionality — then charge for what truly costs you to keep running.

let me know if you can help more.

The "old" model is the best IMO. Sell the software once with like 1 year of updates, and then the user can keep their software at an old version or can pay some amount to get the new version / another year of updates. If you wanna make it look like a subscription ask for a fixed fee first and then a small amount every month but then you don't get to keep the software on unsubscribe (or if you really want to play nice allow to keep using "old" version after defined subscription time like a year or smth)

I agree that this model has a lot going for it.

What it does really well is set expectations upfront: you’re buying a version and a defined update window, not an open-ended promise.

Where I think many products stumble is skipping that clarity and retroactively redefining what users thought they bought.

If users know from day one: “this includes X months of updates, after that you can keep using it or pay for more”, most of the trust issues simply don’t exist.

I see this happen so frequently, and my co-founder and I are grappling with exactly this issue. Our model will rely on subscription rev for a good portion of total rev once we are at full capacity, but we won't be there at launch. The approach we are taking now is deliberately holding back from V1 and V2 the features that we think will be the real value-ads that will entice paid memberships. That way, instead of asking people to pay for a think they previously got for free, we will be adding new features and asking people to pay if they want more - or stay on the free membership and continue doing what they are already doing.

That approach makes a lot of sense to me.

Adding new value and asking people to pay for more feels fundamentally different from taking something away and asking them to pay to get it back.

The moment users feel something was removed, the conversation shifts from value to resentment.

This is the way, in my opinion.

> At some point, the business model changes: subscriptions are introduced, and features people already paid for disappear or become locked behind a new paywall.

If this happens, trust is immediately broken. They have taken away something I paid for. It's a kind of theft.

> Is it ever acceptable to change the deal for existing users?

Not for one-time sales. If it's an ongoing contractual arrangement, like a rental or service subscription, then it's acceptable to change the offer when the contract renews or on terms agreed to in the contract.

> Where is the line between sustainable monetization and broken trust?

There is no tension between those two things. If you make promises, don't break them and there won't be trust issues.

> How do you think about “ownership” in software you paid for once?

If I have paid for software without the terms being a rental from the start, then my expectation is that I will be able to continue to use the software forever (or as long as I have machines that can run it).

I don't expect to get free updates. If I want an updated version, I expect to pay for it. There's a gray area here about security updates, though. A good company will provide security updates at no charge, and feature updates separately for a charge.

This matches my intuition almost exactly.

Especially the distinction between: paying once to own a version vs paying for an ongoing service.

I think a lot of conflict comes from companies blurring that line after users have already built habits and trust.

The point about security updates vs feature updates is interesting too — that gray area is where many products struggle to be explicit.

What I've described is also pretty much the way this worked for all software back in the day.

The two most prominent companies to do this were Microsoft and Adobe, but they actually still do have some one time purchase options remaining. They just stopped advertising them, and made them hard to find on their website.

Also, I have to be frank that both companies are trying to scam people with the subscriptions. Try a full month free, and if you forget to cancel get stuck paying for a full year. The scamming has damaged their reputation more than the actual subscription model.

That example actually highlights something important: it’s not just a technical pricing choice, it’s a perception thing.

When users feel like they were nudged into a subscription in a way that feels deceptive, that’s what really dents trust — sometimes more than the subscription itself.

It’s interesting to see how even big companies struggle with the narrative around subscription transitions.
