"At this point in time, I don't see us removing cookies from our themes or extensions just to comply with legislation in one region of the world"
Typical american attitude as the world starts at Alaska and ends in New Mexico apparently.
Most template theme builders does not just offer its template services to US customers and ideally you want to sell templates to all regions to make your business more successful? I do not see a clause "for american use only" anywhere on this site.
So it would be awfully ignorant to not keep an eye on laws which your users may find issues with on using your templates and possibly monetize that in assisting with a plugin or component?
The fact is that the EU is fed up with large corperations (often based in the US, Facebook, Amazon, Google, but not all) stealing data from people without their knowledge or authority. The cookie law mainly affects non essential 3rd party cookies....tracking cookies, analytics, social media.
So if anybody cared to be informed and knowledgable they would know that cookie removal from templates is not the issue.
You have to state which cookies are being used entirely and cart functions, template settings or login data are exempt from consentual usage anyway. Its the third party cookies that can set on an implied or consentual basis. Originally, all cookie permission had to be set before site usage but the EU have back tracked so cookies can be set but turned off afterwards providing a check is displayed.
The are a number of javascript modules we have written to analyze site cookies and implement a privacy cookie setting to accept or decline cookie usage here in the EU.
There might be a point where EU Joomla users just go to the template providers in the EU as they are now implementing cookie check scripts. Obviously, that wont bother Rocket Theme.
