Not to take Reddit's / spez side, but to clarify, that's not actually what he got in cash - what he got in cash on 2023 was something around 600k.
Those 193mil was in stock. Which kind of explains his drive to monetize users and kick out third-party apps: that piece of paper is only worth that much as long as he can keep the stock value afloat.
This. It's not as simple to get it working as it is on non-free OS's, but with rclone I can get on Linux pretty much the same functionality I get from (eg.) Google Drive on Windows, including have most of the drive with on-demand access (meaning files are not stored locally, but downloaded / uploaded as needed) with a few specific folders synced for offline use. Since it supports a lot of storage services, I suppose it shouldn't be that different to set it up the same way with Proton Drive.
