Possibly true.
How many years ago did Amazon depreciate mobi uploads?
In ancient days* I used mobipocket's mobi creator which could import MS Word doc (not docx) and HTML. Amazon kept the website for some years after they bought Mobipocket (2005) who was once one of the largest sellers of ebooks for Palm OS, Symbian and Windows CE. Even was still there after Kindle launch in 2007. It was crazy that the Kindle was launched with essentially 10 years out of date language support and using mobi. Suggests that Amazon initially concentrated on the HW, maybe even based on eInk reference design for the panel. Perhaps the Paperwhite 2 was the first decent Kindle.
[* Even earlier I used DTP to turn Gutenberg text into an HTML thing with prior, next, TOC and paginated for 800 x 600 portrait on a PMP HTML browser as you couldn't add an app to the Archos 605. It used a 160G Byte HDD intended for video, so we also had fun figuring the best way to re-encode DVD for it and the 320x240 GP2X game console]
