Depends on what content we are talking about - RSS content is viewed within the reader, so it's fine for a RSS reader to copy content and provide it to the user. The issue here isn't copying content, it's that Feedly is changing the URL from the publishers site to their own site - which is distinctly not cool.

Note - I love feedly, and, with the exception of HN, NYT, xkcd and twitter, it's where I consume all my content from the web. This was just a misstep, and I'm sure they'll do the right thing.

Yes and no.

Feedly and other news reader services have de facto permission to gather blog posts at the request of users and then show them to those users. This is a half step beyond that, so you can't really call it copyright infringement.
