I know that's annoying but it's allowed ("paywalls with workarounds" has been the rule for a long time on HN - see https://news.ycombinator.com/item?id=10178989, https://news.ycombinator.com/newsfaq.html). Not that we like the annoyances any more than anyone else does, but it's the lesser of two evils.

But we can change the URL if there's a better one.
