Yes. The sly and roundabout pretext might look like a U.S. mandated hard fork, in collusion with Coinbase and Blackrock, with a "National emergency" wrapper such as, "Bitcoin is being used to fund terrorism and CSAM and blah blah blah, therefore we need to hard fork it to the U.S approved version to root out this evil". This announcement will be made on a Friday at 4:05 PM EST right after market close.

Since none of the MSTR or IBIT shareholders have keys, nor do they run nodes, they have no say whatsoever. And since the market is closed, have no chance to liquidate their holdings. It is simply mandated and enforced. Sound like a Black Mirror dystopian fantasy? This hard fork risk factor is mentioned in the ETF prospectus. MSTR and IBIT shareholders do not get to decide which fork to accept and are left with a rug-pulled shitcoin and the biggest bait and switch of the millennium is concluded.

TLDR; Run an economic node.
