Institutions have rules, and institutions can be made to follow their own rules. They can be made to follow their own rules via using formal processes. In Rules for Radicals, when Saul Alinsky talks about making an institution follow its own rules, he's talking about triggering its official procedures, not so much shrieking impotently about its hypocrisy.
I think that while this sounds good on paper, this does not actually necessarily work anymore.
Back when Alinsky wrote
Rules for Radicals, institutions were staffed by people who believed in fairness, equal protection under the law, and the basic humanity of people they did not fully agree with. Such people would of course follow official procedures to the hilt because they believed in the inherent rightness of the result produced by those procedures.
Now institutions are increasingly staffed by partisan ideologues who only believe in power. Hence why you have AUPs with fuzzy catch-alls and so on, at the risk of oversimplifying it's fundamentally no different from forum moderation in places like Something Awful. I mean, in both cases it's done by troons or troon-chasers, so one similarity is immediately apparent.
Institutions very well might not follow the official procedures if they don't like you, unless a bigger fish decides to force them. And in that case they might very well only pretend to follow them for the sake of appearing compliant to the bigger fish. They'll pretend to lose or have never gotten needed documentation, suddenly require that every i be dotted and t crossed when in other cases they wouldn't, and so on. They'll make following the procedure suddenly become ponderous and excruciating as a punishment.
And you will never be able to call them on it successfully because it will be assumed they are acting in good faith when any honest observer knows they are not - but the key word is "honest," and besides that there's no proof.
In sum,
Rules for Radicals boils down to the naked abuse of better people's good faith all the way down. When there are no better people anymore, it doesn't work. That doesn't mean you don't try, of course, but I would assume success is now a pure dice roll a lot of the time, similar to playing legal roulette in drawing the right judge for your case.
