"Charting a new course for tech competition" by Chris Riley https://blog.mozilla.org/netpolicy/2019/09/26/charting-a-new-course-for-tech-competition/
Interesting read. I wish there were more concrete examples, though, of what they mean by "mandating federation" or "restricting APIs and API policies." Although I guess if there were, then the whitepaper may get muddled by questions of whether a specific example really demonstrates anti-competitive behavior.
