@lina "Detect non-human traffic in advertising to improve user experience and access to web content" - there's the motivation, Google are their advertisers are losing HUGE amounts of money due to this, see https://malicious.life/episode/episode-216/ and https://malicious.life/episode/episode-217/
@gurubob Agreed, although I'd say they're not losing the money, just not making as much money. It's not like they're entitled to unlimited profit at the expense of users freedom.
