Not everyone is fond of Christmas. It's not universally loved. I hated Christmas for close to 10 years after my mom died and before my son was born. This is a perfectly normal reaction to the holidays. That being said, should you spend your holiday hiding time at McDonalds? Absolutely fucking not.
I did find the video amusing, even if it's made entirely of Ai bullshit.
Moon+ has what you're looking for. Syncs to box, Dropbox, gdrive and webdav. And can download from opds libraries like calibre if you selfhost your epubs.
It's not shame so much as deep embarrassment for the current state of our country. We look like fucking morons on the world stage. Thankfully we will move on from this stage in our history, but the stain may remain for decades to come.
