It is, but Figjam was Figma's attempt to attract a non-design crowd and save their financials (at least that's how I see it) so to them it may be a death-blow or at least back to square one.

Miro and Mural will suffer a bit too, but they're a little bit more robust, so they should be fine for a little longer. (Also inVision freehand will now face a problem)
