Why do you say this?
There are many features, supported within the PDF specifications,
that can be implemented with TeX and that *only* Adobe Reader shows 
correctly.

So if you have some things which cause you to say "not TeX friendly"
it is quite possible that you are doing it the wrong way with TeX.
If an effect works in a non-Adobe PDF reader, but does not work
in Acrobat Pro or Adobe Reader, the most likely explanation is
that it has *not* been implemented correctly, rather than that
Adobe Reader is getting it wrong, or is not TeX-friendly.

It may well be that a package writer has not implemented the 
PDF specifications correctly, or to best interpretation.


That is not to say that Reader has no bugs at all --- it most 
certainly does have some, as does any complex piece of software.
I've reported many that I have found, and they do get fixed
--- though not as quickly as one would hope for.

There are people like myself and others who are working to find 
the *correct* ways to do things with TeX, so that these PDF 
features can be used as intended.

There are new laws being formulated in the USA and Europe that
will require PDF documents produced by Government and other agencies 
to conform to the new PDF/UA recommendations --- for Accessibility
for people with disabilities, particularly visual impairment.
This *requires* fully tagged PDF, as well as recommendations
about colour and screen-reading capabilities, etc.

Few non-Adobe readers support many of the features needed
to handle PDF/UA to best effect.


Furthermore, Adobe has just this week announced its latest versions 
of Acrobat Pro DC and corresponding Reader update.
viz.
 https://www.acrobat.com/en_us/free-trial-download.html
 https://acrobat.adobe.com/au/en/products/pdf-reader.html



So please, provide explicit examples of what you think Adobe Reader
is not supporting properly.
I'd very much like to see such documents, run them through validators,
and (if you have the TeX sources) try to identify the causes, which
I'd suspect are actually deficiencies in those PDF's compilation.


Providing (links to) explicit examples is a much more constructive
thing to do than just mouth-off that something is not working the
way you think it should.
