Can an internet provider replace content of websites if the end user is aware of it?
<p>Let's say an internet provider (ex: Comcast, At&amp;t, Verizon) says to their users: Hey we have this new free internet access, however, by using it the end ad content will be changed to our liking -for example they can change Ad Units to show their ads or inject ads into content.</p>

<p>What are the legal repercussions here? If the end user's agree, can sites that serve ads (ex: Google Adsense) sue you for replacing their content?</p>

<p>Also wondering about any other issues that can arise from such action.</p>

<h1>Lots of legal problems.</h1>

<p>I'm going to assume US jurisdiction. <b>I am not a lawyer; this is not legal advice.</b></p>

<p>For starters, the ISP is almost certainly removing itself from DMCA safe harbors, which could open it up to liability for copyright infringement. </p>

<p>There also may be other legal issues, including tortious interference (on the theory that the ISP has interfered with various ToS agreements that it knew existed). </p>

<p>There's probably no CFAA claim, astonishingly. </p>

<p>I suspect there's more. I'm sure that the EU has different (and probably stricter) rules to deal with this.</p>
