Besides this the reasons for regulation are pretty damn compelling. Clear cut case of market failure. You cannot take your business elsewhere to deal with the failings of big tech. It is an industry with a long run decreasing average total cost curve and has network externalities. (Hence why there aren't 27 similar magnitude businesses competiung in the facebook space, for example).
Indeed even if you have no facebook account and have taken your business elsewhere they have a shadow profile of you from your firends and from web trackers and so on. Google have your mail and analyze it even if you run your own server and have no google account. The list goes on from there. The case for regulation is overwhelming, what many of those of us of a libertarian bent want is /sensible/ regulation rather than the idiotic variety that is so prevalent. There aren't many on the right who think you should be able to poison the water or, switch off the taps and increase prices by a factor of 100. There aren't many on the right who think national defence payment should be "opt in"
Anyway these are also esoteric arguments just as their counterarguments are and unlikely to get a groundswell of support either way without a splashy push. The election of Donald Trump was that push for a large number of people on all sides of politics. The counter to that push? Where is that?
