In situations like this, I think the person at the top of the chain that told employees to perform the illegal installations should be arrested and charged. On top of that, the company should be fined into bankruptcy. If the directors knew about it any companies they're involved with shouldn't be allowed to conduct future business in the municipality (or state).
Lots of fans of Luigi Mangione and this hasn't directly killed anyone yet.
I'd say it's just a general tolerance to the idea that the rules we have are baroque and anything goes when trying to reach your aims. This seems fairly cross politically unifying.
Those who want the law obeyed are kind of rare. Most are happy to have the law violated to hurt their political opponents. Then they feel surprisingly aggrieved to have same strategy played against them.
One is breaking the law to punish someone that the law failed to, the other is breaking the law to avoid punishment.
The CEO caused vast death and suffering with the policies he enacted in the name of profit, yet the law didn't touch him. Enforcing what the people think should be enforced isn't the same as enforcing what the people think shouldn't be enforced (mass surveillance). It is, in fact, the opposite.
You have to apply some Theory of Mind. Just like you think you're doing the right thing so do they.
If you condone violation of the law, it will become commonplace. Acting like your violations of the law are fine but others' violations of the law aren't fine is a position you can take but considering that you're in the minority on both, I don't think it's going to result in anything. Sleep with the dogs, wake up with fleas.
EDIT: And I'll add some facts here and an example to my last statement here:
Luigi Mangione's act is a minority approved act actually https://archive.is/hXNhj
So about 18% approve of his act.
And no, in the US the will of the majority is not sufficient. There are damping influences on time-localized desires by design. A typical example might be that California's Proposition 8 banned gay marriage but was nonetheless struck down by the California Supreme Court. The will of the majority is not irrelevant but it is not paramount.
