I check his recent tweet, he's still supporting Bitcoin.
Actually I don't really care with any influencers, he might change his view and support privacy concerns, just like how he hate Bitcoin and now he already own many Bitcoins.
Saylor didn't intentionally chose to adopt bitcoin because he wanted to he did so because the government had access to his asset which got seized back then by the government and he felt the only best shot he has to avert reiteration of that seizure in future was with bitcoin.
Am sure if the government give such persons a better deal tomorrow that's in their favour they won't resist. Businessmen are forever in for any negotiation that still keeps them in good business.
