I resonate with everything said in the post based on my experience building my own projects over the past decade.

I'd say that indie hackers don't need to feel pressured to build in public. You have the freedom to share or not share anything. It's your work. If you don't feel comfortable sharing too much, it's totally okay. People might blame you not open source your entire project. People might blame you for not sharing your personal income. Ignore them. Be yourself.
