Henning,

The topic, is, indeed, not related to engineering, and your analysis
is quite right.

One small point while we're on the subject:

      ISPs charge flat rates not by coincidence or charity, but
because they expect to make the most money this way.

Uneven consumption within flat plans existed before P2P.  Light and
heavy users existed since mail systems were first built in your
favorite ancient empire.  (I once wrote a script to find and quantify
this in dialup days and found what I didn't expect to find: the modem
pool spent most of its time negotiating the speed, and so disabling
the most high-speed option shortened the negotiation and removed the
congestion before I had to decide what to do with the heavy users.)

Users are prepared to pay a premium for consistent month-to-month
pricing.  ISPs are happy to take this premium.  If usage mix changes,
they can change the pricing plans, but consumers will continue to be
prepared to pay a premium for consistent month-to-month spending, and
many ISPs will likely choose to continue to take this premium,
offering different plans to different types of users.
