Flow 1: user wants extension, clicks the browser addons button, searches for it, clicks install. Updates are automatic. Flow 2: user wants extension, searches in Google, finds a third-party website, clicks download, downloads file, runs file, gets warning that the exension is untrusted, clicks install anyway. Repeat for every update. Still don't think the average person wouldn't truat Flow 2 less? Or, to look at it from the other side: wouldn't the fact it was removed by Google make people suspicious of the addon? What was it doing that was so bad that even a garbage pile like the Chrome Store dropped it.
