I don't think there's an anti Alembic vibe per se on BassChat UK (one of the two site owners, Kiwi, has an Alembic Series bass and loves it), its just they are quite rare in the UK and most people have never seen or played one. Couple that with the high prices and thats why there is indifference. Wal are popular but they are UK made and not so rare, hence the excitement every time one of those pops up for sale.
