I don't understand why this is controversial. Tesla wants to diversify it's holding and decides to have x% of it's holdings in form of BTC. BTC subsequently goes up sigfinicantly. Now, Tesla has y% of it's holding in BTC, with y larger than x. Tesla now sells ~100M$ of BTC, which ballparks looks about right to bring y closer to x. This is what many individuals and investors do all the time, it's just rebalancing and it's the smart thing to do.
