To quote the linux kernel style guide:

> Tabs are 8 characters, and thus indentations are also 8 characters.

Yes, tabs are used for alignment as well.

To quote the OpenBSD style guide:

> Indentation is an 8 character tab.

The GTK source code uses tabs when the number of spaces for indentation >=8. This goes against their coding-style document, but if you don't have tabs set to 8 you'll find the indentation broken.

git is the same: although it prescribes tabs if you don't set the width to 8 you'll find broken alignment everywhere.

Oh that's terrible. I guess I'm the one that's been living in a bubble. If that's the kind of people fighting the war on our side, no wonder we lost.

This is horrible and goes against the purpose of tabs. You should NEVER use tabs for alignment, only for indentation.
