Answering this and other similar arguments/observations, and for the benefit of those unable to read TFA:

To answer one potential criticism, it's true that in some sense, blocking and so on for social reasons is not good and is in some theoretical sense arguably harmful for the overall web ecology. On the other hand, the current unchecked situation itself is also deeply harmful for the overall web ecology and it's only going to get worse if we do nothing, with more and more things effectively driven off the open web. We only get to pick the poison here.
