> the entire corporate world for 2 decades while being that mediocre

Because most of the corporate world is mediocre. Employees put up with a lot of BS every day, Acrobat and PDFs are just the icing on the cake. And they're risk adverse. "This is what I know".

It's like when the complaints Windows and Office come around (for decades). People got used to it enough, and don't have to pay for it, so why change.

All periods can be replaced by ? if you want...I'm merely speculating having been in all sizes of companies by now. :)

Your browser is an alternative, if you want it to be! I read PDFs in the browser quite a bit.

This works for about 95% of the documents.

For the rest you need a purpose built reader. Often Sumatra or other open source readers will work with the more complex functions in PDFs (signing, bill processing, etc).

I have Acrobat installed on my corp laptop, but I use Sumatra rather than Acrobat, because I like my reader to simply be a reader instead of a 13GB bloated piece of garbage. I'm also a big fan of my reader not crashing at the slightest breeze.

PDF Expert is excellent. It's insane to me that they don't bring it to PC. It would be a gold mine.

PDF Expert can tap into the Quartz 2D API on Apple platforms, which is likely why they’re excellent. PDFs have been first class citizens on Mac OS X and its derivatives for 25 years.

Some companies are more focused on the PvP aspects of business.
