This is maybe a second time I hear about the Browser Company, but what they declare sounds a bit contradictory. They say, they moved too fast with Arc, now they say that speed is not going to be a trade-off anymore (so, even faster changes, even more to learn for a user?). Open-sourcing a product without its dependency seems better than not at all. What they aspired to build sounds interesting, but ultimately, I’m not sure I would’ve tried that before, and even less now after they discontinued it ¯\_(ツ)_/¯
