Given ARMs dominance of the mobile processor industry for any large tech company to buy them would invite the close scrutiny by anti-trust authorities that none of the major tech companies are particularly keen to attract. Since ARM is happy to license their designs to all & sundry, what would be the benefit to any individual company of buying them out? Little to none: Even if you want to invest in your own CPUs and add your own special sauce (like Apple) then you can do that much more cheaply than the cost of buying out the company by simply buying the appropriate licenses. You can’t buy them and lock out your competitors because the anti-trust regulators would have a fit. I’m sure every large tech company has looked at the pros & cons and decided that the status quo is by far the best option for them & that the same arguments apply to their competitors.
