I’ve used most of the options for this and regardless of the tool I do a terrible job of actually coming back and reading anything in them. Instapaper would probably be my vote for the one I used the most though, connected to my kindle it was nice when I used to travel and could catch up on stuff on the plane. These days I use Inoreader for consuming feeds and it also has a good read later function.
That’s my guess. I get the impression that their “switch to eco friendly plastic” initiative isn’t going well, this might be an attempt to stretch the timeline (by using resold bricks they can manufacture fewer new ones). But totally an uninformed guess.
