I disagree. IMO Author's view is heavily slanted. Several lies by omission and incomplete details.
As for the Bose target audience, there are actually two separate ones. One is what we perceive - WAF/less experienced/Lifestyle crowd but with somewhat deep wallets, and there is actual Bose target audience - basically they clearly to me (from an outsider view, if it's possible) as top range Hi-Fi system, definitely meant to replace the "large" speakers from living room, clearly targeting people who decide and look for hi-end, audiophile audio. Just look at their TV ads. I'm sure you know what I'm talking about. God knows I've met dozens of people fooled by the brand and the promise to deliver high-quality sound for premium cost.
It's an interesting opinion and M240i series tiny coupe which is far smaller and more expensive than even top-tier Accord makes is apples and oranges. I wasn't looking for a tiny sporty lifestyle car, but a practical, but a fun car at a specific budget in mind and my research were on the dot. Accord is all that and more.
BTW: Accord 2.0T (which is one I got) is faster than current BMW 528i [any trims]. Don't know if your wife picked Accord 2.0T Touring, and if it's a different trim then again - it's not relevant. I also disagree with you on the audio system. My Accord 2018 premium audio system doesn't suck, nor in UI or speaker quality in comparison to the premium tier Harman sound in my other car.
