It is quite clear if you look at the source of the data. Flash is (was) Adobe's own rich content creation and distribution system with lots of investment on many different sides. Adobe can make the rules and implement anything it wants at its own pace in its self-contained product, unlike Google and Apple that have to feign “innovating the Web together” while actually solving their own problems. As they got their own sheep to shear (smartphone consumers), it was decided to strangle the competitor. I should remind you how many years it took to make HTML5 video work for everyone on Youtube. I should also point that on older systems Flash video player works (worked) noticeably better than HTML5 video player, making it clear that “open standard” does not, in fact, need less resources. Next time you wonder why modern web is so taxing on multi-core multi-gigabyte system, look this way, among others. As for security, Flash was as broken as any complex system of its age. Most of the attention to its security can be attributed to the fact that corporations only care about security if that's of someone's data they can benefit from. Oh, and it's the same with governments — they don't care about the abstract security for everyone. And any talk about “openness” accompanied by what Google does with Chrome on desktop and mobile is just pathetic. TL;DR It's corporate cool-aid.
