Yeah, you got my curiosity. Especially since you claim the idea wouldn't be popular here.
I would guess something like strong-arm coercion, mostly in the form of legal threats. Most people would buckle under the first whisper of possible legal action.
Blackmail would be similar, but it would require dirt on the site owners in question! And to acquire dirt on an individual, said dirt actually has to exist.
Like with the blackmail spam I get almost daily, claiming they hacked my PC and all my social media accounts (hahaha!) -- it's nice to have 100% certainty that someone is bluffing. When they claim to have a video of such-and-such, and you know for a fact you have never done such-and-such -- you can rest easy. The best defense against blackmail is to live an upright life.
Well, since you are intent on dragging out of me that which I was content to let lay:
Why would a blogger take precious time away from family hours, sacrificing for rebuilding another SSPX, when the grand poobah says "pack up your toys" and "hunker down," encourages liberal independence, discourages vocations, wants to do away with seminaries, etc. etc. etc?
Eventually, after hundreds of articles and several years, it hits you: Bishop Williamson killed the Resistance, despite the consecrations:
While speaking very well about the Roman problem, he nonetheless does all in his power to suppress the Resistance (despite the consecrations).
What good are consecrations and bishops, if nonetheless, there will be no priests under them because seminaries are allegedly passe? Vocations are discouraged. Authority is shot (what a joke: Ever heard of the SSPX, showing authority in hyper-mode?). Congregations are no longer possible (ahem: Ever heard of the 700 priest SSPX?). The end is near! Abandon all hope all ye who enter here! All we can do is wait for the chastisement!
Sorry, but that's all one big bunch of crap.
Nevertheless, when the fence-sitter of 2013-2014 heard what +BW was pitching, they quickly left, and went back to the SSPX (where at least they would have some sense of normalcy, rather than the formless darkness Bishop Williamson was creating, er, discussing).
So eventually, it occurs to you: The Resistance was hijacked.
It is not today that which it was intended to be.
It is not that which it was before Bishop Williamson joined it.
It is no longer a contingency for a replacement SSPX (for the litany of excuses given for the morphing/hijacking).
And finally, you reach the conclusion: Why continue to try to bolster a movement with these efforts, when those who outrank you are actively sabotaging?
Today, it is only the religious congregations that offer any hope (SAJM, Avrille, Santa Cruz, MCSPX).
They had already seen the insanity that comes with a leaderless Resistance, from the USML debacle, and Providence raised up the SAJM and MCSPX (quite against the will of +BW, if the truth be known).
But to the point, eventually, you just realize you are fighting a losing battle, and wouldn't it be nice to smoke some fish, deer hunt, hit a baseball game, and do something more productive?
I believe some former blogs and fora closed because of legal menaces.
But for the most part, people realize that when there is no hope, there is no point.
PS: I should add for clarity that I admire a good many things about +BW, and that I am on good terms with him, and support the independents insofar as they are worthy of support. But I don't have much hope for a Resistance that is being led into the catacombs.
