At a shareholders meeting on Friday, CEO Tim Cook angrily defended Apple’s environmentally-friendly practices against a request from the conservative National Center for Public Policy Research (NCPPR) to drop those practices if they ever became unprofitable.

NCPPR put forward a shareholder’s proposal asking Apple to disclose how much it spends on sustainability programs. If those costs detracted from Apple’s bottom line, the NCPPR demanded that Apple discontinue the programs and commit only to projects that are explicitly profitable. Cook apparently became angry at the group’s request. According to an account from MacObserver:

What ensued was the only time I can recall seeing Tim Cook angry, and he categorically rejected the worldview behind the NCPPR’s advocacy. He said that there are many things Apple does because they are right and just, and that a return on investment (ROI) was not the primary consideration on such issues.

“When we work on making our devices accessible by the blind,” he said, “I don’t consider the bloody ROI.” He said that the same thing about environmental issues, worker safety, and other areas where Apple is a leader.

He didn’t stop there, however, as he looked directly at the NCPPR representative and said, “If you want me to do things only for ROI reasons, you should get out of this stock.”
