At the end they look like they’re taking him somewhere though (out of sight of cameras in an emergency exit hallway) so who knows what they did after.

In France security dudes don’t have the right to touch you for any reason, physical contact can only be made by police forces. That’s why they just block him meanwhile the police is arriving.

At no moments he is mentioning warranty, he only mentioned Apple violating consumers rights

Oh and by the way, “He also smashed at least one iMac and multiple MacBooks”, in the video he’s clearly smashing multiples Iphones or similar devices and 1 MacBook.

He is saying that Apple is violating consumers’ rights. Hence according to the european rights, Apple should give him back his money. Apple refused so he is there to make a point (and destroy devices as you can see).
