You seem surprised? Do you know how things (sometimes) work in Silicon Valley?
Labor is entitled to all it creates.
If you do not feel gratitude to your employer I suggest you find a different one. If you cannot find such an employer over an extended time frame, perhaps the problem is you.
You can feel a job has been worthwhile, lucrative, satisfying… (mutually beneficial)
But feeling gratitude to an _entity_ that puts profits before your well-being is misplaced. Maybe there are exceptions, but not in big tech.
Mostly I choose to work for small companies, getting reimbursed in job satisfaction and work-life balance rather than a big paycheck.
