Of course there is always the option - possibly heresy for Millenials
- to
switch off wifi on your phone. I know, its radical, but it might just
work.

You've raised a *very* interesting point. This survey may be of only
that self-selecting subset of passengers who *do* keep their wifi on [on
the tube].

Which will be most, how many people actually bother switching it on and off?

Does the associated article mention whether they attempted to correct
for this built-in bias?

In the noise.
