Fells like the reason one off pricing is less common is because the model has felt broken since the time of Kazaa (file sharing app from way back), Napster etc. For some reason software is almost exclusively sold through app stores. I don't remember the last time I bought software that wasn't subscription based for a non mobile device. Ok, maybe one app.
Well that and probably the pricing psychology of paying what would be your LTV as a subscriber up front.
That’s also why I don’t agree subscription software is categorically detrimental but more of a trade off. The benefit is there for both parties: for the seller it’s easier to convert people because you’re only asking for the one month or one year price, for the buyer you’re at most out that same reduced price if the service doesn’t work out.
The negative is of course that you don’t own it outright, but it seems a lot of people are happy with the trade off. Apart from HN.
