There are many kinds of bottom bracket these days, but like, not that many. BSA is still extremely common and it's looking like T47 (which has two variants) will be the other common standard going forward. BB30, BB86 exist. Other variants are much less common.
Essentially the entire rest of the article is about ebikes and proprietary batteries, motors, apps, etc, and yeah, that's all true. I'd probably have just killed the bottom bracket section of this article and had the headline mention ebikes rather than try to generalize.
