You've been here long enough to know --- apart from whether or not Nautilus counts as "paywalled" --- that paywalled sites are fine on HN as long as there is a straightforward way to get around the paywall. Complaints about paywalls are, according to the site guidelines, off topic.

Atleast on mobile, I experience no paywall.

What system are you using?

I don't believe nautil.us is paywalled? Wasn't for me, anyway.
