Yes, we are well aware that Flash support will be discontinued in fourteen months (at the end of December 2020).
It's a bit disingenuous of Google to be alarming everyone with the big banner notice advising users to "turn off" Flash, seeing as the rest of the world is maintaining Flash support through to the end of next year.
The actual story is spelled out in the link you provided:
"Chrome will continue phasing out Flash over the next few years, first by asking for your permission to run Flash in more situations, and eventually disabling it by default. We will remove Flash completely from Chrome toward the end of 2020.
If you regularly visit a site that uses Flash today, you may be wondering how this affects you. If the site migrates to open web standards, you shouldn’t notice much difference except that you'll no longer see prompts to run Flash on that site. If the site continues to use Flash, and you give the site permission to run Flash, it will work through the end of 2020. "
As explained in our FAQ, if your web browser tries to block flash content, it's simple enough to enable it in two clicks. It is somewhat irritating that Chrome refuses to maintain the "always allow for this site" setting for Flash content, but clearly they are keen on "sticking it to Adobe".
At any rate we have been actively evaluating other video streaming technologies for some time. We have a lot of content to migrate over, but we are beginning the process now and I expect we will be completely migrated away from the Flash player before the end of 2019.
