I don't think in this case that most people who know what Arduino is would be at all mislead by the title. Being "dead" doesn't have to mean that a company ceases to exist. There are plenty of what I would call "dead" companies that still make money every year. "Dead" can be used figuratively. In this case, meaning that though the company continues to exist, the reason for which many people bought their products is now gone.
Arduino's hackability was its unique selling point. When it is no longer hackable, what is left (of the company)?
Plenty out there to fill the void.

Fair enough, not a unique selling point. But an important one. Without it, who are the customers?
The news describe an important shift, but just describe that it is, no need for "youtubefication" of titles here.
