I don't own any Microsoft shares but I don't think companies should invest in these assets. If I want to buy Microsoft shares, I buy them, if I want to buy bitcoin, I buy bitcoin. There's no reason to mix the 2 together and leave people with no option but to also have some investment in bitcoin if they want to invest in Microsoft.

Of course, companies can make financial investments and it's ok to make riskier investments if they are on a very small scale.
