You do realize that the executives of a for-profit public company have a fiduciary responsibility to maximize long-term shareholder value, don't you? Leaving money on the table with no plausible business justification would invite an executive team's ouster for breach of fiduciary duty. If the board failed to act, activist investors would. The stock market would beat both the board and the activist investors to the punch, punishing the stock mercilessly to bring its price in line with the expected market return rate.
Jobs would not be horrified by what Apple is doing today on the profit front. I don't know who you think Steve Jobs was, but there was one criticism of him that was constant throughout his industry tenure: He maintained premium pricing and high profit margins, refusing to compete on price. Criticizing Apple for continuing his practice betrays a lack of knowledge of how Apple has always operated.
Apple has insane margins and massive profits today. A key difference allowing them to do this is their focus on privacy. If they choose to become another ad company, packaging you for profit, they're certainly risking their golden goose and the current incredible profit levels.
I don't inherently see Apple tracking you, measuring you, and selling you as better than Google doing the same thing.
