Fair point. I'll clarify now: this article, excluding the comments, is about only one type of cold storage: hardware wallets.
I appreciate your effort to ensure I clarify the distinction.
In the future, I'll be sure to specifically state hardware wallets when referring to only this type of cold storage, but I may possibly make a comparison with paper wallets too, and will specifically refer to them as paper wallets.
Also, you may open any of the Bitly links through this site: http://www.getlinkinfo.com. They direct to the website without any referral.
