If you're going to respond to day old threads, at least try to engage with arguments in good faith. If someone (reasonably) suggests that what the government does to attract businesses is a matter of public interest, then naturally my reply is going to point out that not sharing all their commercially sensitive plans and positions is a good start. At no point have I even hinted that attracting business is government's highest priority. It isn't, but nor is "indiscriminately publishing every email ever sent to a public official" automatically a higher one.
There are indeed mechanisms to share confidential information with government officials. One of those mechanisms is that commercially sensitive information shared with public officials gets redacted from emails shared in the public interest. Like all mechanisms it can be abused, but the public is still better off from knowing the general gist that Elon had a lot of email exchanges with the governor, some of which have been published and some of which redacts stuff that was either sensitive business detail or very embarrassing than they are if a similar exchange took place through unofficial channels instead.
