I wasn't aware of this change froch.
I heard something else that might influence Hubs income.
I was reading the hubpages help center. Hubs said that there was a new change; and every hubber had to get their own subdomain name. Hubs isn't sure or not if this will have a positive or negative impact on our income.
I guess we just have to keep our fingers crossed.
To answer your question. My main income is on Hubs. I make pennies on Google Adsense.
