AFAIK, this was expected.
Anyway this law was clearly dictated by private interests, and disrespectful of the citizens, considered as guilty by default (detrimental to the presumption of innocence :/). Another side effect would have been the spyware disrespectful of privacy and net neutrality (and that, I imagine, would not even have been libre or respect interoperability or even multiplateform...). Laws already exist in France that permit to obtain the data "on demand" to a french hosting or internet service provider (that have to keep logs for an astonishing long time :/), respecting CNIL's[1] directives and recommendations that protect the citizens from private investigation and require a judicial authority in the loop to ensure laws are respected (it comes from LCEN[2] which has one good aspect : defining what an open standard with not even a RAND[3] clause).
This kind of law is very sad, as they are not even usable and have prohibitive costs. The adaptation of DMCA[4] (american law) in Europe as EUCD[5] led to DADVSI[6] in France, which included a provision to give an analysis of its "achievements" (the report has not yet been published, it would have permitted to identify where costs went... seems to be IYA :/ around 6 Meuros IIRC).
IMHO, majors just have to adapt their business model or play by the market law and naturally vanish, now that distribution could be in the hands of artists "easily" with Internet everywhere and duplication costs dropping dramatically.
Thanksfully, this "episode" may have created a practical awareness in France (through watching live Assemblée Nationale's video stream) that some laws are detrimental to citizens and that citizens can act to make it change by voting (this may be an illusion). At least, now we have at least two groups (well one and a spin-off) that are recognized as acting for citizen respect by the institutions : see http://candidats.fr and http://laquadrature.net/ that promote free/libre software to politics for one and analyze Internet threats for the other (a kind of french-EFF[7]).
BTW, the name of this law "HADOPI" was in fact "Creation & Internet" but did not speak of creation and neither of Internet as its purpose is to cut it :/ Anyway, HADOPI is misnamed : should be HADŒDPI the D being for Droits translated as "Rights", which have obviously been forgotten /o\.
Sadly, this may not be the end of it, the trend is there among control-freaks people. Let's hope that Internet is really used for our global awareness that we are already used to in the libre community and which provides great opportunities, potentially for everyone : there is really creation, available to everyone (and libre licenses permit to recognize it, promote it and enable collaborative work taking into account everyone initiatives and opening new possibilities).
Do not hesitate to ask more precise questions if some of my points are not clear ;-)
