The world is becoming more and more dependent on computers and Internet. When something doesn't work, like a government website, Amazon or 4G, more and more people will get annoyed.
The more people that are annoyed the easier it will become for governments to "protect" these people from annoyance. They will attack the causes of system interruption. Hackers, unpatched PCs that are part of a bot net, overly creative IT students, computer users that pressed the wrong button.
What if they forbid the use of computers that can be "tempered" with?
This may sound a bit Big Brother and sci-fi, but I don't think it's that far fetched considering the movement towards IT dependence. Any government would love to be able to control the entire network, from the servers to the computers at home.
People kill millions of sharks each year, a shark grabs a surfer and there is talk of killing them all off so people can safely surf. It doesn't take much for a crowd to support extreme ideas.
99% of the people would be fine with it, but 1% still account for the entire Linux community and they have over 5.000 Linux distributions. So 1% is still a market.
