Are there Privacy Concerns with Reddit Going Public and AI in Play?

I want to know if anyone out there has insight about the likes of Sam Altman eyeing sharing sites such as Reddit or Quora a. going public, b. using AI? I realize we don't use our first and last names and our home addresses here, but we do provide sufficient information to watch IP addresses, find out which Internet Service Providers we use, and what MAC address on devices.

Or is this just like ho hum?
