You only addressed half of it. I'm with you that the code is open source, but it's an open source client for Meta's proprietary service. The one original piece of hardware on this "Open source hardware for your Muse" page, the Home Link, only works with an active subscription. And the "grassroots" part is clearly larpy: a "by hackers, for hackers" voice in a Meta incubator repo.

It does not say you have to keep an active subscription for continued operation. The page only says:

  Claim your Muse Home Link
  Free with an active Muse subscription
