I wish the article had more info too. But I appreciate the author acknowledging the limit of their work and not trying to bullshit or skip over it.

I read Electrek daily and find it very useful. They cover a broad range of topic with more insight and voice than the usual crappy blogs that just rewrite press releases or someone else's articles. I particularly like the articles (like this one) that have "Electrek's Take". The Weird Alibaba EV articles are good fun too: https://electrek.co/guides/alibaba/
