are you asking if miners are going to start widespread censoring of valid transactions in bitcoin? i doubt it. even if one did another wouldn't. otherwise bitcoin wouldn't be censorship resistant.

No, they can easily not update to v30 or not run libre relay, but instead continue running v29 with their data carrier preferences and still be within protocol rules. They would thus be exercising their choice. If more become aware of this, the propagation path would remain niche and limited. It's their choice to make. Looking forward to seeing how this unravels.
