Its because some of the reader software comes from 3rd parties. For example the ePub and PDF uses mobile Adobe Digital Editions. So they need to get Adobe's permission to use TTS, and, even though TTS rights are supported by PDFs, Adobe seems to be behind the ball on this. See
Adobe eBooks - Update on Accessibility Support, which seems to be implying that the Hanlin's (EZ Reader's) might be able to do TTS on Adobe PDF and ePub ebooks at some poiint.
The way the Hanlin's handle TTS for PDFs is to switch to different software, xpdf, to display (and TTS) them. This only works for DRM-free PDFs, so it won't work on Adobe lending library PDF ebooks unless you first
circumvent the DRM. Circumvention for the purpose of getting TTS to work is typically legal in the US.
