More than a few of those companies are not actually owned by China. Owning a 10% or 20% share in a company doesn't make them sole owner. Dairy farmers of America didn't get bought out, they are cooperating.
Also this is not a new thing. There are plenty of foreign companies that are owned or have shared owned by Americans, and it's not just the Chinese doing this either. Japanese bought Boston Dynamics for example.
The ownership of a company is pretty high level. It's for financial reasons for the most part, usually there is no interest in changing anything about the company, simply harvesting its profitability. It's not really anything particularly relevant to the average person.
