Are you really just going to defame a company based on nothing but the granularity of Chrome's extension permissions? That's not just irresponsible but downright malicious.

Any extension that interacts with webpages needs that permission. Even if it's just to add a button. Before you go accusing them of selling information about your web browsing, you could at least check if they collect that information in the first place. Which is easy, since a network inspector is built-in to Chrome, and Chrome extensions are just ZIP files you can open up to read the code inside.

Hint: They don't. The plugin inserts a share image into the page, and the image is embedded in the plugin, not hosted on Feedly's server. It creates no network requests at all, so there's no involuntary information passing happening.

Those permission requests are because of an annoying floating "Share widget" that the Feedly extension adds (semi transparent widget near bottom right of every page you go to that you can click to share the page on FB and such).

Fortunately the 'feature' can be disabled.
