Speaker manufactures produce speakers in order to sell them. If the
market wants and will bear the extra cost of biwirable terminals and
crossovers then they will be produced. When enough sales are lost to a
competitor because a speaker lacks the biwirable "feature" then it will
be added since the additional cost is modest. It does not matter what
the manufacturer knows about what is wise or not they are producing for
a market.

Speaker manufacturers had the same problem earlier with cables. Selling
a loudspeaker without cables is inconvenient for customers but selling
loudspeakers with "normal" cables lead to lost sales from the growing
number of people who believed in magic cables. So manufacturers
effectively had to stop supplying cables with their loudspeakers. I
would not be surprised if in a few years time a growing number of
audiophile amplifiers are not sold without power cables for similar
reasons.

What loudspeakers manufacturers choose to say about cables and biwiring
and such is an interesting test of their marketing/integrity. Some
manufacturers keep as quiet as possible on the subject but provide what
the market wants while others actively promote audiophile beliefs.
