I always thought sponsored WordPress themes were tacky. I have come across a few, but it just wasn’t my cup of tea. Why would I monetize my blog in order to help someone else get money? That’s akin to me working at my job and giving someone else my paycheck. 
Basically, sponsored themes had ads or text link ads in the sidebars and footers that are associated with the designer - not you, the user. According to some WordPress users, these additional links can prevent you from conducting your own site monetization. Sucks, doesn’t it?
Many WordPress themes are free, like this one that I just started using. RSS readers, please visit the site to see the new look! The ban on sponsored WordPress themes does not mean that you should not utilize the link back to the designer - just don’t accept any other ads, okay!?!?!
