I think the important thing here is how it affects the result.
Remember Wiggins waiting for Cadel, after sabatage saw him puncture repeatedly. Thats was OK in everyones book. But as Cadel was a firm GC contender. Him not losing time affects Things.
Basically -
Helping riders of a different team not lose time because of mechanicals = good.
Helping riders of a different team win time despite mechanicals = bad.
