FB’s brand is suffering. They understand this themselves obviously. It’s best to liberate new products from the word “facebook” and make it appear as a seperate entity. That’s basically what this is.
That "unified" splash screen is menacing. A constant reminder that wherever you turn, it's a FB property.
With Google/Apple/Microsoft it's quite straightforward, everything they make is clearly their style, their brand. This is not the case with Facebook's properties, they don't have a unified design language or branding. So adding a unified splash is a step in "marking it's territory", I just hate the feeling of that.
Interestingly too, I noticed the box for their Oculus Quests only subtly display the FB connection. And on the recent model, using a different/new 'thinner, all-caps' logo.
