Yes…
Also we and i spoke with many authors
Drop sales like 50-80% of sales.
Some users got lucky and have little more sales but from what i see, from 30-50/ month, now are few sales or 0.
Sad ia that this is reality and can’t do something, just to make more themes and to do marketing.
Also, many have for WordPress 20 usd price so many will buy that theme because is cheaper then other theme.
