Klipfart is such a bad name!

The situation is more complex than that. Basically, there are 4 things forbidden in the French law:
A - Accessing a system fraudulently. That means that you know the system is protected and you don't have the rights to access it, but you still do
B - Maintaining your access to the site while you know that you shouldn't access the site
C - Preventing the site from working properly (deny of service)
D - Modifying, adding or removing some data from the site

The blogger was not indicted for A (he just clicked a link), nor C or D. But he was convicted for B, because he confessed in custody that by browsing the site he knew that the site was password protected and that the intend was to protect the documents he copied.
He also was indicted because it was considered he stole 8gb of documents, but it seems that there is no legal base for this part (you cannot steal a document)!

Names are registered in trademark classes, so you can have the same name in different classes if the name has not been registered in all classes by the first applicant.
This is the list of international classes: http://www.oppedahl.com/trademarks/tmclasses.htm (it seems to be the same as the French classes).

That's why you have a toilet paper and a sport car brands which are both called Lotus.

Well, I don't say there was no hole. There probable was some holes, as for every system. I just said there was no security problems.
First, someone had to pay while you were connected to the service, and at 75bps (upload speed) it whould have been very expensive to try to crack a service.
Secondly you had strictly no information about the server behind the service. It was like a telnet interface, but wrapped by Frante Telecom to a X25 network.
Finally, there was no such things as open proxies, Tor network or bouncing servers, so France Telecom was able to track every connection to the Minitel service to the phone line which did the call.

But I remember there still was a problem with some specific game services. In those services you could win stuff like hi-fi system, TV sets, etc. by just staying connected to the service (without really playing). These services sent some special escape codes to the Minitel to prevent automatic disconnect when no user activity was detected (even if such use was forbidden by France Telecom). And some people were connecting Minitels all day long from vacant offices at their work. But ultimetely, their company had to pay for the game.

I remember the time I was using the Minitel, there was no security problems: no viruses (contrary to my Amiga computer), no password or credit cars number stolen, no fake "sites" (services), no porn for the kids. The services themselves were not crackable (the administration interface was generally not available thru the Minitel). It was very convienent to get phone numbers from the other side of the country, since at that time phonebooks were limited to the "département" (subdivision of France). It was also handy to do online banking, get exam results. But the most used services were "Minitel Rose" (like "3615 ULLA"), were you could have sex chat with (presumably) girls. In fact one of the major french telecom groups (Free.fr) was founded by Xavier Niel, who earn a lot of money during the golden age of the Minitel Rose. But it was very expensive (even if the terminal itself was given for free), since you had to pay per the connection duration (around 0.15$/min for the 3615 services). And it was slow. Soooooooooooooo slow. And ugly too!
