Another problem was that many sites shifted to providing only parts of articles instead of full versions

That annoys me so much, that is the number one reason why I use Feeder more than Feedly nowadays (I manually keep them synced, Feedly is multiplatform and Feeder sadly isn’t) as it has a feature to download the page and use their native app view, so much better than going to the site (even with Ublock I’d rather not go unless I want to comment or see comments, which sadly isn’t a thing for most of the sites nowadays).
