There have been some pretty egregious misuses of eminent domain in the past, but using it for infrastructure is pretty much the quintessential justification. That's basically the only reason to have eminent domain at all. Arguing against it when that's how it's being used is, in my opinion, essentially arguing against the very concept of eminent domain. Which one can totally choose to do! But they should be up front about it, if that's what's going on.
As for the title, I would go further than you do. This is not a misleading title. It is a lying title. I'm usually a pretty big believer in Scott Alexander's Bounded Distrust [0] concept for the media where they very rarely actually, technically lie. This title (although not the article itself), in my opinion crosses that line.

You're giving a blank check to use it as long as it's infrastructure, and as any simple rule, it's prone to get abused way beyond it's primary goal. IMHO the issue is nuance and balance, we should accept that whether it's applicable is an "it depends" matter.
Keeping it too simple and black and white means companies can now strategically place data centers and get the local government to seize all the land leading to it, and vice versa, local govs can nudge companies to target specific places to seize wherever they want. Especially as the plans aren't required to come to fruition.
It should be used for essential infrastructure for public use.
Power lines to a private DC seem to miss on both counts.
