I’m poking at the idea of sportsmanship being as relevant as you’re making it seem to sport—especially at the top—not the concept of cheating or fair play.
But to answer your question, if the sport has a profusely well documented history of electric motor usage that’s over a century long [0], with a huge proportion of its winners using them, then arguably “yes”. For all intents and purposes it’s now part of it! Assuming you’re trying to win, at least.
And in the same way, getting caught is totally fair too. It’s just losing by another name.
