The addictive design is in service of ads. Instead of regulating software, tax ad revenue to disincentivize building a business model around user profiling and tracking.
Why instead of?
Do both.
The downside to this is that services become class based again then.
Instagram is the same service for everyone, regardless if you are homeless or a billionaire, it is exactly because it is an ad based model. Same for google and facebook.
These models are "classless business" incarnate, and people absolutely hate them. It's part bewildering and part bemusing.
Tax ad revenue. Increase advertising prices. Advertisers pay more to sell their wares. Consumers pay more to consume their wares.
