Thanks for the info. I don't know the full story behind any particular residential IP proxy service, but I'd previously decided not to use any of them for a startup's purposes.

As I explained to my colleagues, I wouldn't be able to determine, with confidence, which of the services were 100% legit, and which weren't. We didn't want to accidentally get involved with questionably-obtained residential IPs, etc. That would've been antithetical to our business, and also just not how we operate in general.

(The startup provided solutions in the supply chain integrity space. Part of the technology included bespoke Web scraping, to monitor certain venues for naughtiness scale and patterns over time. Because venues were around the world, and because venues had complicating incentives regarding some of the questionable third-party activity in the venue... I wanted the delicate scraping to look similar to normal consumer users who were in the geopolitical region served by the venue. Instead of a residential IP service, I used an (undisclosed) different, impeccable approach, which won't work for all use cases, but did for ours.)
