No, "the market" means financial considerations created an opportunity that was fulfilled to generate profit. It could be that the economy gained via this FOSS release, and that was part of the consideration, but that would be structural interference by the government (which can be a good thing IMO) working in opposition to the market.
Market forces are often reined in, eg by human rights, those things aren't part of the market operating they're mitigations of the damaging effects. In this case it's an external force (gov action), not the market, that has created the availability of the product.
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.
