That’s just the pretext they give to justify it. The real reason is surveillance. Now they have a way to confidently tie your accounts to your individual identity. And most of these solutions use third parties which will then sell that data as well, so now anyone can tie your account to you without you ever knowing.

Even if the government is barred from surveilling citizens in these ways, third parties aren’t, and the government can just buy that information, no warrant needed anymore.

And these laws never stop at porn, it’s drugs, LGBTQ information, etc. and they can always easily add additional things later with little fanfare.
