Totally industry standard. I've been one of such freelancers in the past. If we were going to boil this down to a scientific dip sample, then yes - I'm sampling a skewed group. Since we don't have any means of doing this, I'm simply writing about my experience of what I'm hearing across, what I would consider, a broad spectrum of our industry. Judging by my inbox of relieved freelancers/industry professionals today, my post is resonating with a whole subset of people who have been quietly suffering thinking there is something wrong with what they're doing/their work; when it's how the industry does business now, that's changed.
