It’s a shame that you feel you have to apologize for writing for a content mill. We all have the same goal, making money from our writing, but we have different paths to get there. No path is better or worse. It’s an individual journey.
Having said that, I really admire anyone who can write for a content mill. I tried years ago, but didn’t last long. I hated the deadlines, not being able to choose my own topics, not being able to write in my own voice. My hat is off to anyone who can do it.
