I think tech companies are realizing that the biggest "mistake" they have ever made was giving so much freedom to the desktop user. They hate that we can look into, modify, and delete files, hate that we can add custom-made software, and hate that we can identify and turn off tracking/telemetry. They realized this with the mobile platform and locked everything down, but by that time it was already too late.

Authoritarian governments (that is, what unfortunately all governments want to be) also love this, since if a few big companies control all computing, they can regulate them to control the public.

Fortunately, there are many computers already in the public's hands (which they can use to perform any computation without government restrictions and without paying/sending data to a company); but more and more people are switching to mobile platforms (and kids start out on these platforms) that I'm worried about the future.
