Shera and French internet lobby La Quadarature du Net both point with concern to a paragraph in the current ACTA text, obliging signatories to provide enforcement measures with respect to at least copyright and trademarks "including the unlawful use of means of widespread distribution for infringing purposes".

This looks like a continued attempt to rein in the use of peer-to-peer networks, says Shera; hence it carries an implied threat to impute some responsibility for online sharing of copyright material to ISPs, a strategy the optimists hoped had been defeated.

"It seems to me that if distribution is to be restricted in some way then ISPs as conduits must be the target, again opening the door to third-party liability and coerced graduated response," Shera says on his blog.

However, both point out that this clause is still in grey type and thus it has not been finally agreed to.

La Quadrature du Net also expresses fears a special-purpose committee established to consider "development" and amendments to ACTA might short-circuit more recognised international bodies. It calls the agreement and the way it has been negotiated "a counterfeit of democracy". The late release of an official version does little to ameliorate the secretive nature of previous discussions, the lobby says.
