Here in in the USA the RIAA seems to have realized that shotgun lawsuits was not working out like they planned and have slowed them down to a trickle. Now they are trying to bully, coerce, threaten third parties like ISPs to do their dirty work. I don't see this as continuing indefinitely. Once an ISP gets sued for damages after terminating a person's Internet connection it will end.
The RIAA, MPAA etc. will eventually change their business model to allow cheap, easy access to their content for large numbers of customers. IMO, this is the only sustainable path forward for them.
