I bet most companies can survive a management self-destruct.
(Also, while a poison pill threat can be a good management decision, taking the poison pill is a seriously bad management decision. So a government can just bet on that.)
Would actually help most places than hinder, I think.
"most companies can survive a management self-destruct" — if it is an oil extraction company, maybe. Otherwise, knowledge and processes can be easily destroyed for good.
If the company can survive then it just means you need to make the poison pill stronger.
I suggest you read the EU Takeover Directive and the associated transposition into NL law. Such shareholder rights plans aren't commonly legal outside the US.
