They're not broken in the context of Unix, where there is a
long-standing convention of assuming tab stops every 8 columns.
 From that point of view, tabs are not formatting instructions,
but are just a way of compressing consecutive spaces.
If tabs are used according to that convention, Unix tools
cope with them just fine.

Tabs used according to non-Unix conventions will break Unix
tools. But that doesn't mean the tools themselves are broken,
any more than the fact that putting diesel fuel in a petrol
car damages it means that petrol engines are broken.

Python is in the awkward position of being expected to run
on either petrol or diesel. It copes by requiring a
particularly refined form of fuel, i.e. not mixing tabs
and spaces.
