But this is a lie, since the original article talked about tax rates on profits
By whose definition?
I don't know if it applies in this case, but very often tax advocacy pressure groups arrive at 'profit' figures by calculations that are a whole lot more bogus than the tax-avoidance the companies themselves use.
Anyway, it's for governments to set the rules, and for people and companies acting within those rules to avoid over-paying. If a big company is breaking the rules, they should be prosecuted - and that's a threat that tends to keep businesses in order where there's anything (like real-life profits) to lose. If they're not breaking the rules, then it's not them who are wrong, it's the rules and/or the critics.
