If in a way Bergger products are an "extension" of Ilford Harman's line of products, I don't mind. As long as there is a wide variety of quality B&W papers at reasonable price, the user wins, and probably the producer as well. It may end up as a kind of monopoly (or niche, depends how you read it), but as long as there is choice and no dirty play, it's fine.
Bergger sells at least one paper that is unique, their extra-premium 100% rag base, and well, there must be a market for that. Their VC papers are really nice as well, and have their own "flavour."
