Do Blu rays require to phone home periodically to validate drm over the Internet? Genuine question., as I have read here that right to play them can be revoked.

They do not require any online connection. AACS has some ability to revoke media player keys, but it does so by encrypting future releases in such a way that the revoked player can not decrypt them (how this works technically is a bit complicated).

So if they decide to revoke your player, it can still play every Blu-ray disc manufactured before the revokation went into effect.
