Trademarks are rivalrous :-).

The "Threshold Pledge" system was a term originally used to describe
what many people would now call the Kickstarter model: an artist says
they want to do X and it will cost $N; people pledge various amounts
until $N (or a slightly higher number) is reached; then the pledges are
collected, perhaps by an intermediary; the artist produces X and is paid
either at the start, in installments as progress is made, or in a lump
sum at the end; X is then released to the public under a free license.

Kickstarter does not require a free license on the result, of course,
but otherwise it uses exactly the Threshold Pledge System.

The mutual-assurance component (i.e., that people send pledges first,
not donations, and then the pledges are "called in" only if a certain
threshold is reached) was actually only described obliquely in the
original Street Performer Protocol (Ransom model) paper [1] -- they
present it in the form of insurance against the artist not delivering,
rather than as threshold agreement with the other pledgers.  Due to this
and other differences, I've always been a bit uncomfortable that the two
systems are lumped together under Threshold Pledge, even though they are
similar (and, in some formal mathematical sense, perhaps the same).

Copyright buy-out is something that can be funded by money raised in a
Threshold Pledge manner, but then again a rich patron could just buy out
a copyright and liberate a work too -- the funding mechanism by which
copyright buy-out happens is separate from the copyright buy-out itself.
(See also the Declared Value buy-out system [2], which is related.)

I'm not sure that compensation and patronage, as traditionally
understood, have anything to do with the Threshold Pledge system (well,
"compensation" isn't a method at all, it's just a word for the act of
payment for some service or product).

HTH,
