I'm work-friends with one of the project leads on Portal, and I felt terrible for him when Portal launched. It was right after all the Cambridge Analytica stuff that gave Facebook a massive privacy-blackeye. I said, "I think it's a great product but I think this is the worst time for Facebook to launch a product that sits in your house with a mic and a camera." On top, it was a bulkier, less flexible, non-portable version of Facetime/Zoom/video chat on your cell phone or tablet. Never understood the drive behind it because it was an OBVIOUS failure right from the get go.
