Fiber goes to copper which then splits out to a large number of homes. The copper line near your home can do multiple gigabit but that needs to be shared with everyone else on the tree.
So selling higher speeds is easy, but reaching them for everyone requires splitting trees with new fiber drops. Providers usually do the first and only some or none of the second in order to sell bigger numbers and compete with Fiber.
A similar thing happened to DSL trying to compete with cable, lets look where that is now.
See chart 15.3, DSL across the ISP industry only provides advertised download speeds 40% of the time. In any other industry this would be considered blatant fraud.
They actually where not doing this before because it's probably a bad idea.
