The amount of plastic waste you produce.
Every shopping trip you get (single use) plastic bags, every food item is packaged individually. Even your plates are often times made from plastic, as is the cutlery (sometimes).
All those plastic cups in every restaurant - it’s disgusting.
It’s insanity.
Also: general waste is labeled “landfill” in some places.
pass.
It’s simple and has frontends for all my usecases. It’s so simple, that you can extend it’s functionality yourself if you wish.
Synchronizing works by just synchronizing the folder where the data lives, so syncthing, git, dropbox, ftp. Whatever you like.
