The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About Killswitch

Chrome provides a lot of safeguards and permission boundaries for abusable APIs. However, it can be easy to grant a permission on a whim and then forget about it. Kill Switch can monitor sites' usage of these powerful APIs and let you know when they're being invoked. Additionally, it can provide a further degree of control by prompting you for permission every session, instead of just once. Please note that this is intended to be a privacy tool, not a security one! This means that a malicious website could easily deactivate Kill Switch and use the APIs regardless of your settings. Instead, consider Kill Switch as a tool to offer you insight into how and when your data is being used.
