In a browser, the top category on Google's "Movies & TV" is "New to buy or rent". The buttons on the page for a movie are labeled "$X.XX Buy" and "$X.XX Rent". In the Google TV app on my android phone, the two buttons are "Rent 4K // $X.XX" and "Buy 4K // $X.XX".
The splash images in the Apple TV app iOS say "Buy or rent it now.", and the buttons on the page for an individual movie are labeled "Buy $X.XX" and "Rent $X.XX".
Movies, on digital marketplaces, have had this kind of distinction for a lot longer than games have.
Paid apps largely failed as a business model though (why would a consumer take a risk on buying a paid app that they can't try before they buy) so most apps that you pay for are free apps with IAP subscriptions... which I guess makes it a little more explicit that you're renting the app, for better or worse.
EG. A mapping app that includes a one time bundle of maps that don’t get updated can be sold as a one time purchase. If you provide continuous updates, which most people expect now, pulling off a one time purchase business model is HARD. The other option is versioned access or time limited support, which is really just a subscription model by a different name. That said I wish versioned access was still a thing. Photoshop CS is still fine for what I want, I’m happy to pay for an upgrade when it makes sense, but a continuing subscription to software that hasn’t substantially changed in a decade sucks.
Strangely, some kindle books actually do meet california criteria of "buy" by allowing a download of the book in .pdf or .epub format.
But when you go to buy them, it still seems to say:
By placing an order, you're purchasing a content license & agreeing to Kindle's Store Terms of Use.
There is no other indication in the item description of this difference.It is only later in your library that it quietly says:
