You get useless links in addition with free templates. They cannot be updated as well. If you are a professional you must know that it is as complicated to edit free templates as it is complicated to edit the paid ones. But you must also know that it is more difficult to edit someones website then yours. If you have full ftp access to the web hosting of the site and to the whole code of the template the removal of all the links from the template is not a problem for you.
