As far as I can tell, Nigel believes that a sink is an electron sink, and a source is an electron source. The industry standard is just the opposite.
No, I believe no such thing, it makes no difference which it is - a sink 'sinks' current down to ground, and a 'source' sources current from a rail either above, or below ground.
As far as I'm aware there is no industry standard?, and the link I provided supported my point of view - sinking or sourcing isn't dependent on your point of view regarding current, which you seem to think it is?.
I notice you said you generally think of 'conventional current', this is obvious throughout this thread - I rarely think of either, it has no bearing on almost all ciruits, I simply think of current flowing from a higher point to a lower point, I've no interest in if the higher point is positive higher, or negative higher.
