I really dislike this comment as it assumes that everything is a competition and needs to make money.

If you just do things for your own enjoyment, then it’s obviously better to do it semi-publicly so that you can connect with other like-minded people or simply give online passers-by something neat to look at.

Plus, if you’re motivated by the activity and not the outcome, you don’t have to worry about competitors at all because you have no competitors.
