To be fair, at least the Tor Project itself makes a rather serious effort to be upfront with its own limitations, etc.

For example, when you use the (recommended) Tor Browser Bundle the start page contains a window containing the following headsup

"Tor is NOT all you need to browse anonymously! You may need to change some of your browsing habits to ensure your identity stays safe."

As well as a link to https://www.torproject.org/download/download.html.en#warning.

That same warning is also present on the main download page: https://www.torproject.org/download/download-easy.html.en
