This is a very angry person.

He claims he's going to explain why the alternatives are crap.

The first he starts off OK. I've never seen this specific design, but fine, you can't securely lock your bike. No explanation on what "securely" means (presumably at least two locks, one through each wheel)

He talks about "wheel benders", but doesn't explain what makes them deserve such a name.

It goes downhill from there. Number 3 his entire argument is "kill it with fire".

They’re called wheel benders because they bend wheels. Bicycle wheels are strong in the direction of ordinary load, but relatively fragile being pushed from the side. In that kind of rack, it’s very easy to apply force to the side of the wheel, because that is the only contact point keeping it upright.

It's written in the "Twitter voice." The angry tone is clearly for humorous effect.

(Also: it's called a "wheel bender" because it can bend your wheel. It deserves the name because it does that, sometimes.)
