Elon is a businessman, and the reason why he purchased Twitter is to make even more profit out of it. If you compare Twitter with other social media platforms such as Facebook, you can notice that the market cap and net profits are only a tiny fraction of what is expected. Hopefully Elon will be able to monetize various avenues in Twitter and generate more profit. And who knows, he maybe able to expand the user base and make the platform even larger than it's competitors. And more importantly, he will be able to make Twitter a politically neutral platform.
I think that is because there are still many people that dont like to use twitter but if there are social media that they will use that will facebook, tiktok and youtube. There are also less ads on twitter. Elon Musk pays huge money on buying twitter so yes he will surely use the platform to generate profits so that he can recover what he spent. He can copy what other social media sites are doing like running multiple ads and adding more features like marketplaces, and others. That way, many people are going to get attracted to use twitter but making twitter free from censorship is already a big thing. This can be the time that Elon will get the sympathy of the public again.
Of course, Elon Musk will change Twitter according to his wishes, namely freedom of speech that is arranged in such a way as to keep it safe for its users. Here I don't know how they do it because Twitter already has its own culture among its users.
He said Elon Musk will make a breakthrough to bring Twitter back to its heyday, here of course he is very optimistic because before Twitter was rarely heard and not as popular as it used to be because many social media are easier for people to use.
