It's hard to read past such a false statement. A couple of their arms are perhaps longer than a small bus, but nowhere near "bigger". It isn't even the biggest squid (see the Colossal Squid).
Articles mentioning footage of live specimens should also note that they are almost universally ill, near death when filmed. They do not belong near the surface. Despite their size, these are short-lived and delicate animals prone to injury.
Also, live specimens have been captured as far back as 2002. So all this talk of "first time" footage is a little disingenuous. Researchers had them swimming in tanks aboard ship more than a decade ago.

Science question here: what's the slit between the squid's mantle (upper body) and the eye? Is that an injury?
Imagine that, coming to the ground floor and seeing the ends of the longest tentacles. You walk up three stories and you still haven't even reached the full height. Then imagine literally running into one of those incredibly long tentacles at ocean depths far beyond the faintest traces of sunlight. Terrifying.
