It seems like all of Silicon Valley, including Adobe itself, has banded together to finally kill off Flash, but the process has to be gradual. A significant chunk of the Internet still relies on the platform, and you can’t exactly force online services and websites to abandon it. Instead, companies like Google and Mozilla have been removing support for Flash and Flash-based services from their products in an effort to starve out stragglers and convince them to switch to HTML5. That’s why Google has decided to stop accepting new Flash-based advertisements on June 30th, and will stop supporting existing ads entirely next January.
