First of all, I don’t like that this topic has gone from discussing issues in general to talking about the actions of particular people.
Secondly, even if I would indeed hear a Posek be matir unfiltered internet, there would be preciously few that I would consider to be on par with those of that I previously mentioned. (And of those few, I’m under the impression that many, if not most, of them have gone on record as concurring to the ruling of R’ Vozner, R’ Chaim and R’ Shteinman.) And even this theoretical Posek would indeed be from that select group, it would still be a yochid against a rabbim, and the halacha would obviously follow the rabbim. So I find it very hard to believe that there is any legitimate heter for one to have access to unfiltered internet, for any reason at all.
Several weeks ago, I was at a chasunah where the mesader kiddushin, a rosh yeshiva from Teaneck, asked the eidim if they have unfiltered internet on their phones, in their homes, or by their offices. One of them admitted that he did, and the Rosh Yeshiva did not allow him to be an eid – they had to get somebody else.
