The examples of mouse movement, really reminds me what bot scripts looked like for Runescape back in 00s-10s. Early scripts were color-based and jumped the mouse around, and those were quickly caught. But over time, bot scripts developed into complex orchestrations; taking breaks, doing random actions spontaneously, moving the mouse naturally, logging sessions on different platforms (mobile, PC), even responding in chat.

There's been plenty of effort put into mimicking realistic / "human" behavior in writing video game bots, and every video game still has tons of bots despite the best efforts of the game devs.

You definitely can't win against bots - but you can definitely make the entire "game" (web at large, in this case) worse off for everyone else through this "always-online DRM" parallel.
