It is typically because the box provides conditional access to their
network. In other words, if you got root on their box you can tamper with
the network to affect other people.
ADSL/VDSL doesn't have this property, because it's not a shared medium - you
have full use of the copper between you and the DSLAM at the telco. If you
mess with that it only affects your link.
GPON FTTP and DOCSIS cable are shared media, and so they don't want you to
connect your own kit to them in case you interfere with your neighbours.
The traditional solution to that is modem mode, where their router just does
the conditional access bit and passes ethernet through to your own box to do
the IP routing.
Unfortunately we've now gained a new front in the conditional access war
which is the in-router VOIP client. They don't want to expose that to their
users, hence they keep it in a locked-down box. That applies to BT, Sky and
other ISPs. It's actually not a big deal on DSL if you don't care about
telephony, because you can still swap out their router and lose access to
their VOIP (and use your own VOIP account instead).
Thus far it seems like these upstart ISPs have yet to get the memo.
(or sufficiently understaffed that they can't implement more than the bare
minimum)

It is interesting that the ISPReview thread indicates it's a standard
1000BASE-BX presentation at the ONT (which is a separate box running Linux,
with telnet access). I'd be very tempted to sniff the output of the ONT and
see what the traffic looks like.
