The boycotts do not target Trump himself. That would risk worsening Trump's behavior and performance even more, IMO. Those boycotts are aimed at a broad range of harmful neoconservative policy and direct actions that the targeted companies contribute to.
Exceptionally, you'll notice that Mike Pence endorses and is endorsed by the extremist neocon organization ALEC, of which Sony and General Electric are members. Although it's unclear to what extent a Sony and General Electric boycott would hinder the bottom line for Mike Pence. What's important is not feeding ALEC.
