> Why should the default be for me

It doesn't have to be, of course. But if you're bothered by something in general in life, and there are two approaches to solving the problem, one that involves others doing the "right thing", or another that involves you changing your approach to it, then usually the latter is much easier to actually address, than the former, as it relies on changing the behaviour of a ton of people.

It's just a tip to make things easier for yourself, without needing others to change. Still, you can do things however you like to, no one is forced to do anything :)
