Faucets aren't viable anymore if we consider they have to earn money from ads and distribute it back to users. And it has been like this since the day Google banned its ads from faucets. Actually, Google killed the faucet industry and consequently the side income of many crypto enthusiasts, especially newbies and young people who were exploring this new universe.
I don't agree that Google killed faucets. I don't remember exact year when they banned faucets, but faucets continued to work few years after it without big problems with revenue from Bitcoin based ad networks. Only revenue were significantly smaller. From business perspective it was understandable Google move. Faucet traffic is low value and there is so much fraud.
There is multiple reason why faucet era has ended. Big hit was closure of Faucethub microwallet. Yes, few new microwallets opened, but they didn't managed to become very popular.
Also, claiming from faucets become too complicated. Difficult captchas, many popup ads, shortlinks and etc. Getting few Satoshi for it simply become don't worth efforts.
Also, many people switched to other earning methods, bounties for example.
I'm pretty sure the witch hunt started in 2016 and by 2017 there wasn't any faucet else displaying Google ads anymore. Faucets exist until nowadays, but like walking deads, zombies. Without Google ads, faucets owners were forced to find alternatives to keep operating somehow, so they appealed to the worst kinds of ads disponible on the internet, such as pop-ups, malicious links, pornography and endless sequences of short-links. All of them low paying ads which turned the faucets into completely useless websites for extra earnings.
Without Google ads, the industry died in less than 1 year. At least, if faucets were clean to claim, like in the old days, I think we could still consider them an alternative, especially for newbies, because they could profit by claiming in quantity, instead of relying on the quality of the faucets. But it's just insanity to spend 2-3 minutes in a website to earn 20 satoshis per claim on the best of scenarios...
About Google's decision, well it's up to them as a private company to decide to which kind of website they want to relate their ads, but fraud and poor traffic quality remains even without faucets. At least through faucets they were helping the miserables of the world to start their crypto journeys from zero.
