I work in a large FAANG company. For more than 10 years, I made the error of not publishing my personal work and ideas. I didn't like the rules about personal works, publishing opensource or social media communication... you are subject to gate-keeping by your employer if you are an employee. That's quite different from my previous experience in smaller companies in Europe. I found it very off putting: you had to give up ownership. I thought it was demeaning that even what I create in my own private time would be owned and attributed to someone else.
My choice of not publishing anything however was a very bad one. I didn't understand what power is: the continuity of the Self into the Other, where you find your-Self at ease. If you don't assert yourself, you give up not just your power but your very identity.
The truth is that power is dialectic. If you don't speak up, you have no power. Both in what you create, and in the relationship of and with power that you live, you are constantly redefining the boundaries of what you are and what you are not. If you remain silent, you loose.
