It's worth pointing out that retaliation, itself, is not illegal or even necessarily morally dubious. If a company were to retaliate against an employee for stealing by firing them no reasonable person would find fault with that.
Only retaliation for a protected activity is illegal. Is interfering with or undermining the company's business prospects in service of a political opinion a protected activity? I don't know, but it would not surprise me if it were not.
To be entirely honest, I'm not sure I think it should be. I can certainly imagine a lot of scenarios where I would not approve of people motivated by certain political opinions actively working against the interests of the company that employed me.
