What is the most useless app that you have seen being given as a subscription?
For me, I tried a 'minimalist' launcher app for Android that had a 7 day trial or something and they had a yearly subscription based model for it. I was aghast. I would literally expect the app to blow my mind and do everything one can assume to go that way. In a world, where Nova Launcher (Yes, I know it has been acquired by Branch folks but it still is a sturdy one) or Niagara exist plus many alternatives including minimalist ones on F Droid, the dev must be releasing revolutionary stuff to factor in a subscription service.
Second, is a controversial choice, since it's free tier is quite good and people like it so much. But, Pocketcasts. I checked it's yearly price the other day, and boy, in my country, I can subscribe to Google Play Pass, YouTube Premium and Spotify and still have money left before I hit the ceiling what Pocketcasts is asking for paid upgrade.
Also, what are your views on one time purchase vs subscriptions? Personally, I find it much easier to purchase, if it's good enough even if it was piratable, something if it is a one time purchase rather than repetitive.
Lots of words and lots of assumptions. You can improve a product and release another version with a paid upgrade, while the old version remains completely functional. If your works have made the software substantially better, people will be happy to pay for a new version. If you aren't adding real value, having the last version should not be necessary.
Updates can both add real value, but not be worth piecemealing out as separate purchases.
Your biggest assumption is that you don't have the drive to better a product if you don't have a subscription model. It's simply not true. You can and in fact must work to better your product if you want to stay relevant in the market and drive your customer to pay for a new version of your software.
Then, you proceed by describing the positives of a subscription model. While you're not wrong about those points, you are leaving out the negatives and forgetting that every business model would have symmetrical points to be made.
There are some context in which subscription model are suited for or in fact even necessary, but the harsh reality is that now every software is turning into a subscription model only for two reason: you can extract 10x 100x more money for your customer, and you can lock-in them in order to keep them paying. This has proven to be detrimental for the quality of the softwares too: software loose interoperability and compatibility, updates are so frequent and gimmicky that they can be a problem, etc etc.
Totally fair if you don’t like the subscription model.
But I am genuinely curious what you think I’m making assumptions about.
