I knew that it was likely intended so they could legally coordinate with those ISPs to censor people that are saying things the "establishment" disagrees with.
Corporations never censor (in modern times) for the "establishment". They censor, if at all, for themselves (and tehmselves). Mostly they prefer to not censor and instead brainwash though. That is easier and with less risk.
Just look at how cigarettes are not bad for your health. Or Asbestos is totally save. Or pesticides. Or that there is no climate change (which in fact Exxon scientists openly (as in expensive journals) told back in the 70s while their PR department launched a big "there is no climate change" FUD campaign)
The corporations in charge of the media ARE part of "the establishment"
Strange, because all the Trump fans say he will drain the swamp of the establishment (rofl). But of course Trump is a big part of the corporate establishment and was always proud to say it.
So sorry if I mixed something up here, its hard to understand if half a dozen of groups use the same phrase and always mean something else.
