Re-using addresses to me is a good feature of bitcoin. Why are programs trying to stop that? When you have a donation address, a payment address, an address just associated with your company you would want people to know that address. Let the user make up their mind and do what they want instead of the program, right? Almot %90 of the users here paste their personal bitcoin address in their signature. It is more of a common practice to re-use addresses then anything and when a program or someone tries to just change that, questions will be asked....hence an entire thread.
Address reuse is privacy pollution.
And that should up to the user to do with what he/she wants to do with his/her privacy. Why would other people care what I do?
Because it's not expected of the user to know how to optimize their own privacy. It's up to us to set sane defaults and educate users about what they sacrifice by deviating from that.
Unfortunately, Bitcoin privacy is pretty bad and reusing addresses pretty much completely deanonamizes you. Every one you interact with can see you r entire history and balance. It's pretty atrocious.
Not only that, but by doing that you damage the privacy of everyone that interacts with you. It's in everyone's best interest to discourage address reuse, especially when the software uses deterministic wallets and backups are not an issue
