I'll just copy my post here:
It's one line, please remove it if you don't like it. There's nothing to stop you doing so. These are commercial templates, so I have every right to advertise in them. If some component you bought had text in it that contained the name of the company you bought it from would you consider that unethical? I just made the text hidden so it would not disturb the layout of my member's sites.
As a member of the OpenSEF team you should know that just having text on your page that mentions something that is not the core of your message will not affect your SEO unless you basically have no other text there. In that case your SEO would not be good in the first place. Your inflammatory topic is clearly meant to incite people and cause more conflict.
That's my stance. A request please, if anyone has a beef with my templates or my service, please contact me privately first, if that does not satisfy you, post on this forum. Ken just has a new target in his sights this week and it happens to be RocketTheme, posts such as the one he made could be considered to be slander as they are technical and factually inaccurate.
