My understanding is that the thermal expansion is taken care of near the stations with a telescoping section. So the tube then has to be free floating, i.e. not attached to the pylons.

http://www.leancrew.com/all-this/2013/08/hyperloop/ goes into this in more detail (and is skeptical that it can work as described in the Hyperloop Alpha white paper).

That link doesn't even entertain the notion that the tube is not fixed to the pylons (even though it quotes the white paper saying exactly that).

No, it specifically addresses that. The white paper says that rather than rigidly fixing the tube to each pylon, it would be fixed to a damper that would "absorb the small length changes between pylons." The problem with the white paper's approach, as the blog post explains, is that the length changes are far from small.
