Buy it directly through Computershare, who knows you could get fucked if you buy it through, and hold it, with Fidelity when this pops again. If you go through any broker, best to find out how to directly register it in your name as soon as they settle in your account. Remember, SIPC insurance covers only what you bought them for not what you would've sold them for. DRS doesn't require SIPC insurance because you always own your assets without a middle man.
Buy more directly with Computershare, then cancel your dividend reinvestment plan so the shares you bought are "booked". This would be the same thing as having the keys to your cryptocurrencies vs only using coinbase.
