Tax evasion is and always will be, illegal. Tax avoidance is legal and undertaken by every single sane tax-payer who pays the minimum tax but computes that amount in accordance with the tax rules. The courts are available for redress if the tax authorities think the rules are being bent. Judgement is a legal matter and not one for debate by armchair moralists.

Those who don't like the way some tax laws operate in the realm of complex company operations should lobby the law-makers not those tax-payers working in compliance with the law.

Yes. People who disapprove "tax avoidance" or "tax optimization" should reflect on the idea a few years back:

High-earning professionals like medical doctors in a North European country had a very high marginal tax rate (well over 50 %). They also had long working hours. Thus, many opted to reduce their work amount; it's better to take unpaid leave and mend your house, rather than to work in a responsible job, get close to zero net compensation, and have a leaking roof in your house.

This is called tax optimization or tax avoidance.

Now, the government notices this and proposes a "tax on work that was not done with the purpose of avoiding tax". Will you approve?

This kind of mechanisms are what we talk about in tax avoidance and tax optimization.
