Comparing this report (which shows flash plugin usage within chrome users) to this report (which shows general flash plugin usage) - it seems only 2% of chrome users have no flash plugin compared to 3.9% across all browsers.
Depending on how you look at it, this is either a sign chrome users don't need additional help getting flash installed or that google is simply catering to their users who have a special affinity for the flash plugin - you decide.
My guess would be this is some special strategic bond between Adobe and Google to further push flash since silverlight is by far the fastest growing plugin technology - but that growth is partially tied to the growth of Windows 7 which comes with silverlight.
A while back I got tired of everybody tracking me online so I cracked down on permanent browser storage. I ended up getting rid of all cookies on browser close and ran these commands:
rm -rf ~/.macromedia/Flash_Player/*
rm -rf ~/.adobe/Flash_Player/*
chown -R root.root
chmod -R 0600
The flash cookie problem was solved and I have not noticed anything has changed. Of course, I don't really see much flash other than flash ads - so it might break some things I am unaware of.
On windows the same directories are stored elsewhere - but the same overall technique should work fine I would think.
what exactly does "upgrade movement" mean?
That means that it would appear shockwave users do not frequently upgrade. They probably had to install the plugin to view something and then they forget about it. In this case, this may leave more people open to attack.
