(Yes, I would recommend a change of title.)
The step is a significant one, and Roblox has taken one other measure recently, restricting chat a lot for minors (https://x.com/Roblox_RTC/status/2043723470899437623) . I think this is a move to satisfy people concerned with child safety, not a cash grab. I think RB hq probably know they're making tradeoffs of keeping parents happy, while devs will be annoyed/fewer. But everyone can still make games and play them with trusted friends. Likely damages the network effect (Roblox's multiplayer aspect being one of its best parts), but oh well.
