There's reasons people are "anti" big companies, or quick to give them a hard time.
The big companies tend to stop focusing on the software and what their software is meant to do.
What do they focus on - you could write a book about that. I would throw in; egos, money, "power", stocks, and the fear of losing what they have which ironically seem to drive them to do even more things that turn people away from them.
So people start using Foxit, or free or smaller Anti-virus programmes, or Linux, (even!) and then (sometimes) the big companies cop on, like Symantec trying to slim down their anti-virus etc., Adobe speeding up start times for Acrobat Reader.
As for helping them, I'm slow to do that - there's been a bug in Acrobat reader all the way through version 8.* I didnt report it.
The bug was that the default (for graphics programmes) switching between pan and zoom in/out shortcuts didnt work properly - why should I report that, they MAKE Illustrator and Photoshop! - so they could not have missed this bug. And the message in the fact it's not fixed?
Have you ever tried to use their forums - I did early last year over a period of time and I've rarely
ever had to wait so bleeding
long for pages to load - what's the message there for me ?! Btw, I know one probably reports bugs elsewhere.
I still use Acrobat Reader (or whatever they call it these day). It is my favourite reader

but as you can see I'm not too happy about it

* the bug
using spacebar to pan, if you then click on Control key you can zoom - select an area with mouse and zoom in, or zoom in increments by clicking mouse - adding Alt key to the mix zooms out. It's the most efficient way to switch between panning around and moving in and out. Once you start using that comfortably (if you need to navigate that much) you'll never use another way out of choice.
the bug is:
Currently if you press spacebar and then Control key nothing happens
