My theory is that one way to reclaim the web is to place more emphasis on individuals and their contributions, and less emphasis on platforms and their opinions. Additionally, there needs to be sustainable business models where the end user's incentives are aligned with the platform's. People are willing to pay for things they want if there's real value for them.
I'd like to see platforms act as utilities, not systems for enforcing opinions or curating content. I want to be given the tools to decide for myself what type of content I see, who gets to contact me, and I don't want to be force fed ads.
