Hmm? Large customer of leading widget manufacturer decides to make its own widgets in-house instead and keep the build minus buy money (plus possibly getting a better widget). Totally normal market practice. Large player in widget market has low marginal cost and deep pockets, sells widgets at marginal cost its competitors can't match. Also totally normal market practice. Competitors exit market or are relegated to minor market share, leaving de facto sole survivor. Also totally normal market practice. We could be talking about chrome just as easily as IDA pro here.
