If you want to fix ICE, then by all means, attack the problem at its source! Take that well paid Github salary of yours and fund the ACLU and other lobbyists fighting the good fight. Write your congressman. Call your congressman. VOTE! Campaign for the correct congressman. Code for your congressman. Push for policy that makes ICE employees (and all government employees) more accountable for human rights abuses. All of these actions will be more effective than campaigning for ICE, who will just migrate to a different cloud code review tool if the contract is cancelled (gitlab, bitbucket, or whomever else).
