Sure, this is the age-old “knife used to cut steak is indistinguishable from knife used to stab people” thing. Tools are inherently amoral; only people can have motives we can celebrate or condemn.
Is the value provided by Cloudflare to public so great, that we are willing to pay for it by enabling mass surveillance?
turnstile is not a public good, it's a private product, promoted to private entities that want to achieve a certain outcome that is beneficial to them privately.
The mass surveillance is a side-effect - an externality that cloudflare does not have to pay for (but we as netizens pay collectively).
It is the role and responsibility of gov't to regulate away externality (or make those who benefit from it pay a cost somehow, to equalize said externality). Unfortunately, like with climate change, nothing has been forthcoming, and only a few people care about the actual damage enough to even talk about it.
So it will go on, and the masses do not have a say.
