This! These are all well-known DAWs, while Bitwig is still very new and not so well-known. They should make their product more interesting for new potential customers, but they're doing just the opposite.
It looks like they just released it without checking what's already available from the competition. All competitors offer more for the same price or less. I think most potential customers will go for an already established name, unless some less established company offers a more interesting product.
Maybe the guys at Bitwig just don't want to sell many copies. All these pesky new customers asking stupid questions
