My job is on enterprise servers administration and some development consulting. I do collect money from my customers. I am well paid for that.
For being part of open source projects and documenting my work here I really do not charge anything. I am trying to avoid any type of ads also.
If you think that any information you obtained here is worth of some money and are willing to pay for it, feel free to send any amount through paypal or bitcoin, or dogecoin (wow!).
