Considering the ease of reading .epub .mobi or .azw3 formats on electronic media, why aren't technical books these days published in such formats instead of the usual PDF?

Kindle is owned by Amazon, which aims to own as much of the world as t possibly can. The primary ebook format used by Amazon for their Kindle readers is .azw, which is a proprietary format, one that is owned by Amazon and licensed out. T can make money with the licensing. ePub is an open-source format. No one owns it. Amazon can’t make money off of it. Follow the money.

Alter PDF: All You Need to Know

I will give a brief example how some PUB files created by authors did not behave as expected. They were not optimized for mobile devices and some layouts did not work on the phone. This caused some serious and unexpected problems in certain cases, which caused very unfulfilled satisfaction when reading PUB file. Sometimes authors do not even know that their book is actually in a fixed layout format (which is a waste). I have talked to authors of PUB files and even one of them knows that his PUB is not optimized in any fashion, but he does not care at all, and this is even worse than knowing how poorly crafted they are. I think they usually think that if their design file is formatted badly, then it is better to not bother because of the lack of knowledge and/or skill than it is to bother because.
