Nautilus is actually an example that supports how in-depth science reporting can be difficult to monetize. I really like many of their articles in the publication, but there was a major incident a while back when they were severely (many months, even longer than a year) behind on paying their writers.
I actually happened to meet a writer who had this happen to them, but this incident was also publicized in an open letter (source: https://nwu.org/an-open-letter-from-freelancers-at-nautilus-..., with discussion about this on Twitter at: https://twitter.com/aznfusion/status/941051077922869248). This happened in 2017, and I'm not sure how long it took to get resolved.
