I would say quanta magazine is a counterexample
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.
The future seems bleak.
ETA: Oh!! The link re: the Twitter thread is gnarly! I hope this got resolved and the freelancers got something out of this.
