It is important, I think, to understand that personal computing is just one part of the picture. "Enterprise" environments (governments, businesses, large organizations, etc.) have demanded many of these "features" even before Google started implementing them. Your workplace, by and large, does not want you, the replaceable person who happens to be sitting at the keyboard, to be in full control of the device that they own and which is connected to their network. Often this is made more explicit by the device just being a "thin client" or other totally locked down narrow viewport to some other computer you can't even touch. It sucks and the general trend of workplaces trusting their employees less and less has been demeaning and degenerative to the point of often fostering self-fulfilling prophecies of mistrust (don't trust anyone => get untrustworthy people => bad things happen => don't trust anyone => ...).

However, it is important to also understand that the employee is not the only stakeholder. Government agencies answer to legislators, nonprofit management answer to donors, corporate management answer to investors, etc. There are layers of compliance that must be considered as well (internal policies, external regulations, different insurance costs, etc.). It is unsurprising that these fewer but generally deep-pocketed entities have an outsized influence on the market compared to more numerous but less moneyed end users. If you refuse to serve the former, you may quickly find yourself out of business.
