Yes it is. Flash is one entity that runs across several browsers. By definition it's more popular than each one of them. If there's a bug in Chrome, it affects only 30 percent of the browsing market - the Chrome market. If there's a bug in Flash, it affects 95 percent of the browsing market. That's why it would've been much better if Adobe open sourced Flash a long time ago, because then each browser could do their own implementation of Flash, just like they do with many other open specs today, and then if there was a bug in Chrome's Flash, it would've only affected the Chrome market. It's too late to open source Flash now, but we're doing that instead with alternatives like the HTML5 video tag and WebGL (for animations).
