I'm not the person you asked, but here's my reasons.
I'm on Linux and there no longer is a supported version of Flash by Adobe. (Apparently there is some NPAPI to Pepper bridge though, to get Chrome's Flash working in other browsers.)
I already uninstalled before that, because I wanted to force HTML5 for sites that dynamically switch between Flash and HTML5 and because I wanted to nudge more sites to support HTML5 by boosting the stats of people who don't have Flash installed.

I'm using Firefox on Ubuntu with Flash (flashplugin-installer) and it's still receiving updates. It's an older version, but it has been working fine with every Flash site I've visited so far.
