From CNBC

Twitter’s board of directors currently has 11 members, with Musk becoming the 12th board member, at least until Dorsey leaves next month. Musk will also control more than 9% of the shareholder votes. Functionally, that means he’ll need plenty of support from other board members and shareholders to win their approval for any future proposals.

But considering the fact that Musk is an extremely high-profile and outspoken investor, with more than 80 million followers on Twitter’s platform, the world’s richest person is already in a strong position to push for changes. And Twitter’s rapid addition of Musk to its board shows that its leadership is at least willing to entertain the billionaire’s ideas.

It's okay to have hope but let's not put all our eggs in the Elon basket. He still needs support from other board members to have ANY impact at all on their operations. Considering they aren't looking for ways to be subsidized by the government like every other Elon venture idk how much they'll care about his thoughts and opinions. This can go a lot of ways including nowhere.
