Thinking about it this way, what if you worked for Facebook or Twitter as WFH and they blocked these sites. What now, do you move? Get a new job? Suppose they also block VPN traffic as that is a known way around their blocking.
I thought ISPs were classified as common carriers and thus are obligated? Or are we saying we _don't_ want net neutrality now?
So it's all good your ISP can do whatever.
Censorship is just a classification of what they are doing. In both cases, it is selectively application of blocking of contents based on one's political believes. Calling them censorship is not an assessment whether they have a legal/illegal/legit/reasonable/unreasonable cause to carry out such acts.
I just find this approach somewhat ironic.
