I'll take your point: there seems to be a US specific problem with ebooks.
In particular, the lack of numbers from the dominant player (Amazon) makes trend analysis all the more difficult. Yet there's still an increase after 2020:
On Amazon, are you merging publishing and distribution as a single activity ? I thought Amazon in the US only accepted self-publication under their name and the rest of the Kindle available titles are from each publishers only using Amazon as a printer/distributor.
E.g. who would you assign as 50 shades of grey's publisher for the ebook version?
Amazon has both a self publishing arm (kindle direct) and a traditional publishing arm (amazon publishing). Like most traditional publishers they have a variety of imprints (e.g. 47North for Scifi/fantasy). They compete for authors via the same mechanisms other publishers do and have notable non-self published authors (Greg Bear jumps out to me as a scifi fan).
I don't know the specific legal contracts involved with 50 Shades of Grey's ebook distribution but I'd assume that Vintage Books bought those rights after they became the publisher for the book.
