Not sure if it is helpful to reduce every issue to a one-dimensional scale of capitalism/socialism. Particularly this specific issue is about privacy culture, corruptability of big tech, government and use of technologies, surveillance, etc... There are so many more societal and just plain epistemological axis than just socialism/capitalism.
And the results are pretty similar to the 2018 vote on cancelling their public broadcaster, which also highlighted questions of corruptibility of big companies, but was not around privacy, technology, or surveillance.
That can also be read on the scale of "privatize anything because the state should just make 'laws'"/"have a public sector to offer basic services to citizens", that is a debate in Europe
