There are issues everywhere. Companies that had their cables deployed made sure that any regulation that would eliminate that moat heavily favor them, either by forbidding other companies to deploy and forcing them to lease the already deployed infra or by forbidding them digging ir whatever bullshit.
Very few companies wanna get into deploying their own network (both in the states and europe), but the few that do make money out of it. I would be really surprised if Switzerland is any different.
