If what you're referring to is temporary copying for technological processes, exception 30.71, that's a good example of an exception that is framed really broadly in a way that is prone to misunderstanding or abuse.
An example is broadcasters arguing that all of broadcasting, from the ingestion of content until the public performance of the work, is one technological process and, therefore, all copies need to be exempt. It may be that, properly framed, an exception like that is an appropriate mechanism to deal with data mining and artificial intelligence. We have to be very careful to frame these exceptions in such a way that really targets them toward the intended purpose and doesn't leave them prone to exploitation in other senses.
