I don't think that will ever be possible. Devs are always choosing what to show. If you don't implement a single nip, for instance, you are blocking those types of posts. And devs cannot implement everything anymore. So, what you see will always be what the devs chooses to code for you to see.

Thank goodness for the open source community desk clients and browser clients. I disagree. Again why aren’t they disclosing this censorship on their prospective app stores? Marketing as censorship free is disingenuous. I’m beginning to view Nostr as a walled garden especially when censorship is implemented on the relays themselves. Marketing Nostr as censorship free is a lie. Can’t be censored is a lie. You can argue that people can start their own relays but that defeats the purpose of social media. The marketing should change to reflect this. Again I’ll reiterate, can’t be censored is the competitive edge that is being marketed. If the main relays that are recommended by Nostr and app devs are walled gardens this should be disclosed. How is this any different to any other mainstream social media? What is the competitive edge? 
The keyword is censorship-resistant. There are as many opions about censorship as there are clients and relays. Some things should be censored... it's the moderators with their agendas that are the problem.
