You're describing the ones that smell like rent-seeking extortion.

How about the Signal model, where you get a free messaging app with published source code that runs on multiple platforms without trying to lock you into any of them, and its modest operating expenses are paid from donations to a nonprofit?

Or the Linux model, where a minority of users with the resources or technical capacity to make improvements are given the opportunity to do so, resulting in free software that anyone else can use too, and anyone could fork if the existing maintainers became abusive?

Or the Substack model, where you pay money for a service with no ads on it?

Huge dominant conglomerates being abusive is not unexpected. But why do we need huge dominant conglomerates? Let them cease to be.
