I love Dropbox, I pay annually. I use the open source client https://maestral.app/ on the Mac for workstation use, but also integrate other systems with my Dropbox account using their API. If someone built an open source Dropbox server that sat on top of S3 compatible storage, I would not only use it, but pay to have that optionality to get out of Dropbox if they ever enshittify. I can recognize form and function worth paying for ("value"), but still want an exit plan. It's not about the spend, it is about data sovereignty. This is colloquially referred to as “vendor and third party risk management.”
