At this point you need to follow up with convincing technical details of why Dropbox needs the circumvention to counter the accusation and rebuild the damaged trust.
The reason for needing Accessibility API listed in your response is pretty vague, especially for those Mac users not having Microsoft products tainting their systems.
I've deleted Dropbox from my Mac for now. I'm not installing it back till there's reasonable explanation and remedies.
I'm not affiliated with Dropbox, but compare the UX of Dropbox (type in your admin-password and that's it) with the one of Steam (opens the System preferences and forces you to make manual changes). Both need to be allowed accessibility access for one feature or another, but only one of them provides convincing UX.
For us power users, the "official" way is better, sure, but what's the percentage of power-users compared to normal users who actually enjoy the office intrgration and other things made possible by the accessibility API?
I would be happiest if it didn't do the dirty thing and also didn't offer office integration. Maybe that's the change they need to make. But if they insist on doing the things that need accessibility, then the current solution is so much more convenient than the steam dance.
