If by “afloat” you mean “a flotilla”, then yes.

Don’t worry, this was just the Chinese campaign. The Russian one is still going strong.

At least email has some tools to help mitigate the issue, like SPF, DKIM, and DMARC. They aren’t perfect, but they are loads better than telephony.

IP hasn’t been an admissible form of identification for over a decade now.

Now, suppose that someone hasn’t been piggybacking off of their neighbor’s wifi, and it leads to a household with multiple adults renting the place with internet included in the rent, how would you determine which specific person to take legal action against? Secondly, in order to actually file the suit without it being a waste of time, they would have to have independent data showing that this person did indeed do the action and aren’t just making it up, in which case getting the IPs from a third party would be completely moot.

If I remember, tech companies are generally those whose primary products are digitally based. And technology these days has essentially become synonymous woth the internet.

And perfectly demonstrates the flaw in OPs reasoning.
