The more I talk to lawyers, the more I'm convinced that a fair majority of lawyers are, consciously or not, extremely defensive about their job security.
Think about this: If I give you the simplest piece of advice in legal matters, I'm heavily encouraged to declare I'm not a lawyer and that you should contact one.
This is the only profession where I see this be so reliably the case. In other risk-averse professions (tax compliance, health) there is always the obvious "You should talk to a professional" but even in health it's not as heavy-handed. I've never seen a doctor say "I'm a doctor but this is not medical advice" when giving basic information.
And I understand the superficial reasons why this is done, but there's just as many reasons not to get your buddy-mechanic to fix your car without them making you sign waivers.
This matters because the people who most need legal advice are those who can't afford lawyers. Makes me very uneasy.
Also to your CCO, I would say that if we were limited to what we would understand day-to-day, there would be no more learning. This is one of the core pillars of free software after all.
