>Your counter analogy is also a bit cherry picked. Guns and vehicles used for committing crimes are seized, but the vehicle makers and gunsmiths are not ordered to go substantially out of their way to prevent criminals from using them, although they do stamp serial numbers.

Internet companies aren't being asked to proactively block piracy sites either. They're asked to block IP addresses associated with known piracy sites, as determined by the courts.

>Also, ore and parts suppliers are not required to ensure that the buyers of their material comply with all legalities with the use of their materials. There’s a line of absurdity that this crosses

...only because the government aren't nervous about "ores and parts" getting in the hands of criminal or rival states. For many other items, suppliers are required to seek export licenses for certain goods[1], which is arguably an equal or higher bar than what you're describing. Such items aren't limited to stuff like explosives or munitions, it also includes benign stuff like certain metal alloys, and semiconductors. Also, Banks and other financial institutions are required to proactively look for sanctions evasion activity.
