What is the big deal about Elon Musk wanting to buy Twitter?

I’ve heard all sorts of angst about Elon Musk wanting to buy Twitter. But I don’t understand what the issue is. If it is that he might open it up to “unpopular” views, is it really that bad? If it is that he might start spreading “misinformation”, it has been seen that Twitter has suppressed the truth and pushed the misinformation view as is (see the Hunter Biden Laptop as an example). So what is the big deal?
