Yeah, I have a Max Lumi and I feel broadly the same way. My hardware has been great, I use it daily and have read 100s of books and written thousands of pages of notes on it, but wouldn't necessarily recommend it to others because I think mine has already stopped getting updates, the GPL violations aren't great, and the cloud stuff seems a bit dodgy.
On the cloud stuff though -- note syncing has support for WebDAV, so I've fully disabled the Boox Cloud integration and all notes get synced to my self-hosted OwnCloud server, which is nice.
I'd love to figure out how to install some stock Android or Linux on it down the road, though Boox's notes + reading apps are really quite good, and likely very optimized for the hardware.
