That’s a really impressive lack of understanding of the economics and culture of technology and partnerships.
Law firms don’t operate like normal companies because the lawyer’s guild in every country I’m aware of has enough power to make comprehensive legal services companies illegal. If you wanted to use a partnership to argue it makes sense for technology companies to be partnerships better to use accounting firms, except they do have all those officers. Even with similar restrictions on non-guild members telling guild members what to do. And every big accounting firm grows and then throws off a professional services firm (Accenture, CapGemini, etc.)
Or look at other industries that used to be dominated by partnerships, like investment banking. As soon as the restrictions making it illegal go away normal corporations took over from partnerships.
