You should always use a new address every time you receive bitcoins.

Not sure I agree, and for sure know such a practice can add to paperwork in some instances. Example: lets say a website creates a "donation" address (public of course). If 5000 visitors decide to donate to that address OR to 5000 unique address generated by the site, what is the difference? The same coin count is received. There is no security risk since the private keys are not on the site or on the server presenting the public receiving address. The only issue I see is if the site needs to keep records of the individuals sending coins. Therefore it would come down to a business decision in that regard, but not really a security decision. The VPN providers I use are paid via BTC and they generate specific addresses for me to apply my payments when I renew. I understand that because my payments have to be registered against my account, especially since they don't have my name or raw IP to source. I feel the rotation of public addresses is about business conduct and not security. Please feel free to differ. LOL!

Using a static public key is not a security issue it is a privacy issue. These are two different issues.

If you use one single address then anyone can see exactly how much has been donated.

Clearly correct! If you read my posts you will see I am all about privacy and anonymity. There are instances where a site uses one address but I wouldn't. They are still secure via BTC, just out in the open for donation levels.
