If a product is so wildly successful that your company makes massive profits, then the employees that made that product are entitled to that success as well. Why do executives, who usually don’t have a hand in actually making the product, get so much more than the people who made it? Pay exists because there is no guarantee of profit on a product. Nobody will work for the promise of getting paid someday when promises don’t put food on the table. Yes, a company should pocket a certain percentage to fund future projects and as a safety net, but everything left over needs to be divvied up across the entire company, not just the c-suite.
Reducing the price to stop making profit is fine since more people can afford to use the product. Assuming you hit a user cap, the price savings allow customers to spend that money elsewhere thereby increasing purchasing power. If you are selling to other companies, the other company now spends less meaning an increase in profit. This goes back to your customer’s company spreading the savings back to its own employees.
Operating costs plus a certain percentage as savings.
You seem to be trying really hard to invalidate the point with whataboutisms as if a single gotcha will invalidate the entire argument.
