What do you think about the fact that most of bitcoin users don't understand how much information they provide by reusing an address, is that an overlooked aspect of bitcoin privacy?
Since it is not a security risk, it's normal that not too many people worry about that.
Actually this may not be a security risk initially, but it becomes one if there is any data leak that ties such addresses to us, a good example is the Revolut data leak that happened recently, all the clients that their data got leaked have both their privacy and security compromised.
The thing is, we are all guilty of this, because there are many situations were address change is not necessary, take signature campaign payments as an example, or a donation or merchant address. It is also impossible to be deanonymized with just a bitcoin address, other factors have to come into play in order to link a real-life identity to a bitcoin address.
You can be deanonymized with transactions histories from the same address, remember all data regarding your transactions are on a public ledger, so it is possible to connect that singular address to your physical identity if you mistakenly involve transactions from another address tied to your on-chain transaction histories with the former in your personal dealings and it points directly at you.
To further break this possibility, you should reuse address the more and use coin control to ensure you carefully select the UTXO sets you use while initiating a transaction, that way you escape possible deanonymization from a dust attack.
