As for censorship, it is no longer a matter of actual resistance but merely if and when the pools choose to do it there are 11 entities who decide what transactions go in (or stay out) of almost every block, and simply the 2 largest can impose censorship on everyone else with 100% success. This is not some future risk but a present reality, and it's not sustainable if Bitcoin is to remain a permissionless currency.

As we stand today, Bitcoin is not a censorship resistant network, rather it just happens to be a network that is not currently being censored. As with other forms of centralization (hardware, firmware, ...), the role of mining pools must change for Bitcoin to exist as a truly decentralized currency.
