Yes of course, the day he tweeted that tesla would accept BTC the market went up up and then the day he said they would stop it went down down.

It probably would have been better for him not to tweet but to be honest the price dipped below their buy in point of $34k per BTC so he suffered as well.

I think maybe it's because their people knew this would work out in the long run and the decline in sales of tesla cars to ford or criticism they would receive if they were seen as supporting an environmentally negligent technology wasn't worth it.

Now they've come out in opposition of the tech they can claim to be responsible again even knowing the price would certainly recover.

Or nobody knows, and people with that much money have nothing to lose really.
