This blog seems to be one person's passion project. They can write whatever they want to in whatever manner they want to.

They're not required to weather your scrutiny or to pass your bar exam to be allowed to post whatever they want.

Aside from that, you raise good points, but you can very well ask your questions directly to the author using the comment section of their blog, you're somewhat more likely to get a satisfying answer there than here.
