The posted article presents a naive point of view.
In tech, it's very common for those who resign to be walked out of the building immediately.
In corporate America, the idea that you'd give THEM more notice than they'd give YOU in the event of layoffs is one-sided.
By all means, plan your exit carefully. Ensure your own security. If it's an amiable parting, try not to leave them in a lurch. But all of that is you being nice, not something you have to do. If, as is often the case, you're leaving because you're very unhappy with your situation, there's no point in prolonging it. Go.
Yeah, two weeks is customary in the US and most employers will either take you up on the offer or walk you out the door but pay for the two weeks anyway because it's not a lot of money in the grand scheme of things and it's just easier that way. (and if they weasel out of that two weeks pay it's not a lot of money from the employee side.) I did give 2x longer notice once and it ended up fine but wasn't really necessary.
What is important is that if there are vesting dates and things like that, wait until those happen rather than assume employers will let you mean employed through notice periods, vacation days, etc.
And, yes, there are doubtless circumstances where "I won't be working here as of next Monday" is probably the prudent approach.
