I would call it maybe 'relativizing'. Like making everything so relative that anything could happen in theory while taking away attention from the fact (hence similarity with whataboutism) that it just (or mostly) happens in one specific case. So Oil industry would align with 'Left' if 'Left' aligned with Oil industry, but that is not relevant take since it is not happening.
And using Musk is not example of this case because he is not part of oil industry.
