There are chemical solvents for many plastics, they're used for things like shaping plastic objects and welding things together all without use of heat. Splash a little on and the plastic goes soft like taffy. You can easily deliver them with a squirt gun, so long as the gun is made of a plastic the solvent has no effect on.
Good luck trying to fly when your rotor strut is flopping around like a rubber band...
That perjury clause is a real problem. If you did check whether you or your company owned the intellectual property you're taking down, and you don't own it but take it down anyway, that's perjury. But it's also perjury to claim you checked when you didn't even if the IP turns out to truly be yours.
Perjury is a federal crime, with a 5 year prison sentence attached. Given how many false takedowns happen and how many are automated, it's astounding that people aren't going to prison over this.
A private citizen perjures himself once and rarely gets acquitted. You can even get convicted of lying to the feds because the FBI wrote down something untrue about what you said to them. But if an organization engages in a criminal conspiracy to commit perjury hundreds of thousands of times...nobody in the government cares.
