The biggest problem with Frontiers for me is that there are some handy survey articles that are cited like 500 times. It seems that Interdisciplinary surveys are hard to publish in a traditional journal, and as a result 500 articles cited this handy overview article for readers who would need an overview.
The article I checked was in a reasonable quality, and it's a shame I can't cite it just because it's in Frontiers.
I don't understand the point of this article at all. How would an instance federate without processing these information? (And I think the IP cannot be collected; not sure why the author indicates so without source.)
Not sure if the author understood anything about the fediverse, either. Feels like an AI-generated article, honestly...
