I suspect that the sky-is-falling panickery of Silicon Valley software engineerdudes over on Twitter is overwrought, but I'm more intrigued by the conversation of trying to predict how a mass influx of real people will painfully force Mastodon gatekeepers to start listening to users for the first time.
Up till now, it's barely ever moved past the "we engineers can engineer solutions to social issues through engineering decisions that make trouble impossible" mindset, which is delusion.
