I'll take a little of the publisher bait (I sit on the board of a "dinosaur paywall publisher"). I'd like to question the popular thinking that publishers do not add anything of value. There has never been a time in history when it has been easier to publish your research output in any number of other places than a paywall journal. You can post it on your own blog. You want a DOI? You can post it on The Winnower. You…
Doesn't "publishing with a paywall journal you acknowledge that your field values the prestige awarded by that journal" contract with "it's not the publishers that are dictating the prestige". Your arguing that if I post it on a blog, it gets lost in a sea of other content. If I publish it, then I get validation. If I understand correctly, you are saying that one of the fundamental reasons for publishers to exist is…
No. the grandparent post is pointing out that journals do provide value in practice, because people care that someone was published in the journal. This has nothing to do with the publisher, and everything to do with the people reading the papers.

You're confusing "ought" and "is". The system, as it works today, isn't that -- you can push for that change, but as it stands, journals add value in an academic career.
Until a researcher can actually submit their research to a tax dollar funded committee (or whatever other alternative people dram up), and get that weighted as heavily as a journal publication when applying for tenure, journals will not be replaced. Working towards replacing journals may be nice, but the parts aren't in place today.
