Note that you have now shifted the goal post to the future tense :/. The reality is that Apple Silicon only started shipping only in a subset of Apple laptops... they currently--which is all that matters, as in the future Dropbox isn't somehow prevented from compiling their software to be "native" Apple Silicon if that somehow actually matters in an important way--aren't a big chunk of anything, including macOS users.
