This is only half the story, not the full reason. There's more to it
than that, and that is the concept of "accessibility support", which
is central to any discussion about the accessibility of PDFs but
missing from what you have said.

My point is that this statement is incorrect as it stands. It would be
correct to say "some screen readers" but not to generalise to "screen
readers". As I pointed out in my statistics for Ireland, complex data
tables in PDF files may only be able to be read correctly by something
like 35% of screen readers in this country. I'm not sure whether 35%
is right because I don't know the full details of accessibility
support for PDF data tables in screen readers, or even exactly what
versions of screen readers people have.

Monir, you have to factor in the concept of "accessibility support",
because that gives the essential context within which statements about
the accessibility of PDFs of any other online technology can be judged
as true or false.

All the best,
