Wallabag looks great, if a little homebrew. I signed up and had to laugh that the default "Welcome to wallabag" article could not be retrieved. Regardless, I decided to give 'em 12 bucks and see how it goes.
Just to add that you can also self-host it, and it supports Kobo as well. I once stumbled upon but didn't investigate further since Pocket just worked so well. I guess now I will have to.
It’s the lack of nice sync to an articles directory that’ll be missed. I’m also bitten by this shutdown.
