I completely agree with this, but if you don't mind me saying so (and even though it's one I use myself) the phrase 'spirit of the regulations' really annoys me.
Regulations don't have a spirit. They have words, and words have meaning. So, when a new regulation comes into force either the words used within the regulation prohibit a particular activity or they don't. If they don't, it is not the duty of anyone bound by the regulations to say 'oh well what they actually meant to stop us from doing was X so we'd better not do that anyway.' Regulations are regulations - nothing more, nothing less. They are certainly not guidelines, advice on best practice or some sort of code of conduct. If you are in breach of a regulation, sanctions apply. If you aren't in breach of a regulation, the fact that the regulations aren't fit for purpose doesn't mean you can still be sanctioned nonetheless.
What is meant by people using the phrase 'not within the spirit of the regulations' is usually nothing more than an activity that isn't precluded by regulations but would have been if the lawmakers had thought of it. But if the regulations don't stop you from doing something that if the lawmakers would have prevented if they'd thought of it, the lawmakers have nobody but themselves to blame for not drafting their own regulations properly. It is of course entirely open to the lawmaker to change the regulation where they see people are taking advantage of what the regulations don't say, but as you say that happens all the time, as in the context of say tax laws.
You're absolutely right. I was just trying to represent the way our detractors will view it, not endorsing the view - which I see as having no merit whatsoever.
One example is that people will think it somehow underhand or manipulative that we've managed to take ourselves outside the scope of the related parties rule despite us obtaining sponsorship income from state-owned Emirati companies, which is then not subject to the fair value test, when our legal owner is an Abu Dhabi royal and a minister in the UAE government. But under UEFA's rules as drafted, and despite UEFA's assessors seemingly trying to argue to the contrary back in 2014, the better view is that we and our sponsors aren't related parties.
We're perfectly entitled to exploit that, and we did, by valuing two UAE sponsorships at values that UEFA's assessors wanted to reduce. But why shouldn't we? As you say, the rules have been drafted in a particular form and we work within that.
In a previous lifetime, I worked in the UK central government, including on some legislative drafting projects, and I had that attitude then, too. If you produce regulations that don't achieve what you set out to accomplish, then you don't bleat - you recognise that you fucking well should have drafted them properly. If UEFA wanted different rules over related parties, they shouldn't have cut and pasted IAS 24. If they wanted a different definition, they should have devised one.
Unfortunately, fuckwit sports journalists either can't or wilfully refuse to understand this. They're reacted hysterically, doing their bit to create a febrile atmosphere around the issue that, according to the NYT, leaves UEFA investigators/adjudicators afraid not to punish us for fear of their own reputations. That's really disgraceful reporting.
