Ethically questionable to feel entitled with the intent of damaging, sure, but exposing a flaw that calls into question the authenticity of a merchant’s claims, e’hem the most valuable merchant who sells you their own insurance and generally holds the title as the most valuable company in the word.. I suppose an egalitarian perspective would hold that what the tweet expresses and does fair game so long as it does not incite a viral abuse campaign. Or I guess if it was a startup or smaller company I would feel different. Apple doesn’t need any favors, they are doing just fine right now.
