The sort of reasoning that puts spikes on speakers but doesn't really
know why. Some say it's to "couple". Others to "decouple". What do
you think they're for?

You can do either... you can couple the speaker to a huge mass, or you can
decouple it from all (possibly resonant) masses. Either method works, and
you can measure whether it's working or not (or you can just put your hand
on the floor and feel if it's vibrating).

Reading at face value, that reply states that spikes either couple or
decouple the speaker from what it's standing on. Depending on which
you WANTED them to do.

This can't be right. What DID you mean?

It depends on what you do with the spikes and where you place them. The
original intention was to couple the speaker through a carpet to a solid
floor, so the floor and the speaker move as a system. But they can also be
used with a flexible material like a rubber pad to decouple the speakers from
the floor.
