I am not censoring blockchain data, I am merely filtering it. This project depends on unfiltered nodes so there will always be many of these kinds of regular nodes running.
But, you are censoring block chain data. If someone asks for it, you may block it. That is the very definition of censorship.
I don't see it that way.
If a government censors sites on the internet (let's say they also censor proxies, VPNs and Tor for the purpose of this discussion), then all ISPs in the country are blocking access to the site. You do not have any way of accessing that site again.
In Bitcoin, the vast majority of providers will still provide unfettered access to all data through their APIs. This is just a small project that prevents you from requesting certain types of data. I can't (and for the record, will not) try to get other people to block said transaction data; that would undermine Bitcoin anyway. So given the circumstances, how is this new API going to be blocking people from getting said data from elsewhere?
