Many countries have some sort of "Competition Commission" whose role is to determine if acquisitions/mergers are bad for either the market or consumers. This might be for monopolistic reasons or other negative issues.

In this case, a platform buying up cross-platform software to eliminate support for competing platforms is clearly causing harm to consumers. In similar situations, a government might legislate to force companies to be either the pipe/platform or a content supplier but not both, to eliminate precisely this type of anti-consumer incentive.
