I know this isn't your actual question, but I think you should consider if the tone of your article represents the company you're trying to build. To me it reads as informal (comparison table "yes but weird), jokey (meme at top) & one-sided (can't find one point you lose at). It feels like poking at your competitor, not like an attempt at a neutral comparison. Now they're poking back via lawyers.

Maybe you do need a lawyer in this instance, maybe not, but if you're committed to this style when dealing with competitors you'll likely need a lawyer in the future.
