I don't think it's necessarily generational. DSis and I are both around 50 so Gen X and had exactly the same upbringing by the same post war baby boomer parents, who were of a generation where they could remember times before fridges and use by dates, so needed to use their judgement to decide whether something was safe to eat, plus they couldn't afford to waste good food so if it was good/safe to eat, it was eaten and throwing it away because it had passed a very conservative date or had been out of the fridge for a few hours just wasn't on their radar.
But DSis and I have a very different outlook on life about many things but especially food safety. I can sometimes see DM looking at us and wondering if DSis was switched at birth.
She won't eat anything that's been out of the fridge or even approaching a use by date, let alone past it, yet I'll happily stretch use by dates by a day or two, cut mouldy bits off cheese etc.
As for egg safety information, reliability of what you read and critical thinking skills, I've read the 'lion eggs info' and my take on it is the kitchen cupboard is fine, except perhaps if you have a tiny kitchen with the cupboard above the cooker and massive windows that let loads of sunlight in but is nearly fridge cold at night because otherwise, most kitchen cupboards will be fine.

I wouldn't take the above info as telling me that I must or even should keep eggs in the fridge (and even that site says keep them in the box rather than the egg keeper in the fridge). And for the OP reading that eggs 'should be discarded if left out for longer than 2 hours after refrigeration' well that's clearly nonsense that can safely be ignored.
As it happens we don't have the egg storer in our fridge, which is only a few months old, but we wouldn't use it anyway - we go through around 25-30 eggs a week (both usually have 2 a day for breakfast and then other cooking/baking too) so would constantly be fiddling around with boxes (the out of date eggs I referred to in my previous post were some that I'd bought reduced because bizarrely it's illegal in the UK to sell eggs that are less than a week before the use by date so I often use this to my advantage.
