What is happening at Twitter now is expected. You do not expect someone like Elon Musk to spend such a huge amount of cash on an app and not dictate what will happen there or fire some people, especially those who he felt prevented free press. Twitter will be in a better position with Elon running its control than it was. More changes are expected in time to come too.
It's almost inevitable for Elon Musk to be a dictator in some way. To be honest, I don't care whether dictatorship is good or not generally. As long as it does work in its own way, I have no problem. If all the changes have continued in a good way, Twitter will be great.
Whatever Elon Musk does with Twitter should not be seen as dictatorship. Anyone who feels that it is will only be hurting himself. It is his money and business and he should do whatever it takes to keep it going. If staff feel they are not happy with his decision they can leave on their own or get fired. There is no one that can put that type of cash on an investment and want to be soft with decisions. Businesses are not conducted like that or else it will collapse.
