Or the opposite - companies with the most draconian and rigid RTO mandates end up with high attrition. Anyone who can work anywhere else does so, and the company becomes a collection of misfits over time.
Currently the hard-RTO companies in the news are clearly doing it for silent layoffs reasons as there are simultaneous leaks of 5-figure attrition targets.
Maybe a strong FTC/DOJ stance on antitrust, plus the top-down mandates will lead to more small company innovation as well.
Companies need to make money. High performers will go to companies that make tons of money, even if relo to Sahara is needed
