GDPR does have a clause (Art. 22) referencing "The data subject shall have the right not to be subject to a decision based solely on automated processing[..]" , however:
1. the scope of GDPR is about rights of natural persons so anything about a company or organization Google Ads account is out of scope. A non-profit organization (AFAIK DroidScript is one?) is not a "data subject" to which that article can refer.
2. even if it would apply, it does not require "that companies be able to explain the decisions of black box algorithms", it requires "at least the right to obtain human intervention on the part of the controller, to express his or her point of view and to contest the decision" so if you complain, express your opinion, and then the company has a human review the automatically gathered data and respond "yep, we looked at it and our decision stands" then that's compliant, that GDPR article does not require them to provide you with an explanation, only with a human intervention.
