You could also save yourself a lot of effort (and avoid being the constant subject of manipulation and exploitation) and not use centralized, capitalistic platforms like Instagram. Try Pixelfed ( https://pixelfed.org/ ) or something.
- Tiktok: "I don't want or need this" -> Delete forever.
- Pixelfed: "I don't want or need this" -> Don't install.
- Instagram: "Still get a ton of value from seeing updates come in from family, don't want the option of getting deep into reels" -> Strict daily timer.
- YouTube: "Still get a ton of value from the network of content published to the platform consistently, don't want the option of getting deep into shorts" -> ??? self control.
The dilemma I have with YouTube feels like exactly what the OP's app is intended to solve.
And I want to be where my people are. So I choose to make informed trade-offs.
