The fact that many have commented in these forums, and others have, I am certain, sent you e-mails about this, should tell you something.

Even so, Firefox has maintained backwards compatibility because XP still has a large user base. We put the app on our desktops so that we could access Dropbox without using a browser. Giving unsupported browsers as examples is disingenuous. It is whether or the users are still out here. They shouldn't have to hold back their development to continue supporting a product whose creator stopped supporting over a year ago. Yes, there are valid reasons not to upgrade it (I have one system at work that cannot be upgraded beyond 2000, yet), but that doesn't mean other companies are obligated to continue supporting it just because you won't/can't upgrade. XP users have many reasons to do not upgrade, and DropBox knows them all. Google Drive does, but with Chrome no longer supporting XP, it's likely just a matter of time before Drive no longer does as well. Windows XP is no longer supported by Microsoft, by Dropbox and by many, MANY other companies, and those that do still support it will likely move away from it as well.

As far as I know there are no third-party clients for Dropbox at all (not counting those meant for mobile devices). As far as I know, there are no replacement apps that will allow you to continue syncing Dropbox on a Windows XP computer. We don't set policies, make decisions or have any input into the process.
