Having Dropbox on Linux distros running on Arm processors would make a huge difference for people who own Raspberry Pis. Pi 5s have much more computing power than my cheep Ubuntu desktop that ran Dropbox ~15 years ago. I am highly considering making my main driver a Linux running on Arm device. If that happens, I'll have to reevaluate my cloud storage solution.
I'm not opposed to compiling code from source if need be. But asking for source code (even just for the client side) seems like a harder battle than asking for binaries.
