Tim Cook CEO of Apple also publicly disclosed he owns bitcoin.
Both Cook and Zuckerberg have a favorable view of bitcoin, so any reserve proposal has a better chance of passing under them than it did with Microsoft and Bill Gates,
who thinks bitcoin is a Ponzi scheme. Another difference is Zuckerberg has a controlling interest in Meta, so his voting power could be enough to push it through. Time will tell.
CEO or individual owning bitcoin is completely different from an organization or corporation investing in bitcoin. Most large corporations have to go through a voting process where no individual, including the CEO can decide because it involves the interests of the entire corporation. News of Tim Cook holding bitcoin broke a few months ago but had no impact on the market and Apple has never announced plans to invest in bitcoin, this shows that even the CEO cannot influence the company's decisions.
Bill Gates is no longer the largest shareholder and Blackrock is the 2nd largest shareholder of Microsoft, so Microsoft not investing in bitcoin is the decision of most shareholders, don't blame Gates.
