I mean, it's good for the insurance company to help it make more profit, but it undermines the arrangement of how insurance works. So, I would argue it's not what they should be doing from a societal perspective, and there should be regulation that stops them doing that.
If you take it to the extreme of them being able to tell with 100% certainty who's going to need a payout when, they'll just arrange it so they'll never need to pay out. They'll not do or stop doing contracts with those that will need a payout, or they'll raise the premiums such that they still gain. Insurance would become pointless and customers are better off saving for their own expenses.[1]
I've made this comment before. I'll just quote myself on the basics of how insurance works, to make this point clear:

> With regards to insurance, that industry depends on ignorance. If an insurance company had perfect information (psychic, precognition level) on who's going to need a payout when and who's never, then the point of the insurance becomes nil. They're not going to enter contracts with individuals that result in a net loss, only with those that result in a net gain. That can look like them just raising prices until it results in a gain. If that's the case, people can just save and use their own money to cover the events that will happen, because insurance would not be of any benefit to anyone at all.
> The way insurance works on a basic level is they know a percentage of people will have a set of events happen to them, but they don't know who. They have a large amount of clientele and charge everyone such that the revenue can cover the expenses of the unlucky percentage of their clientele and make a profit. To the individual, the insurance expense results in significantly less than what they would pay would they be part of the unlucky percentage without the insurance cover.
> The arrangement is founded on the ignorance of who belongs to the unlucky percentage. The economics of insurance don't work without the ignorance. So yeah, at some point, algorithmic pricing of insurance likely ought to be banned if we still want insurance to exist on a meaningful level.
[1] As a parenthesis, it being better to save is in a closed system sort of way. In reality, the fact that a lot of people would still get insurance because "that's responsible" means end providers can raise their prices on the assumption that most of their customers are the insurance companies and insurance companies "are rich", so there would still be a price difference. That's kind of what you see with health insurance where people that are not insured can get lower prices than those that are, such that it may end up even cheaper than the copay. That's for example, kinda what can be seen with styropyro's healthcare story:

> 5:39 so my insurance denies the CAT scan right I mean that's a really really common move for health insurance they just like to blanket deny procedures
> 6:21: but uh but the stupid part is is then I got billed $3,300 for that scan with insurance and the even dumber part is that I I got a quote from my clinic on what it would cost me without insurance and it was only $1,400 so because I have this insurance it actually cost me more money to get this scan like how is that how is that even possible that is the stupidest thing in the world
I imagine he can't see it because of the stress and anger, but that's probably exactly why the insurance denied it, because they were being billed way too high by the provider. If the provider billed the company what they billed regular people, they likely wouldn't deny them at the start. There's a limit to what anyone can pay, even insurance companies, and they have to put a stop at some point.
Back to the original point, imagine what that looks like with end providers that don't provide separate pricing between the insured and the non-insured, and where most people have insurance. The end provider would just give the higher pricing, the one for presumably rich insurance companies, so you would still save money with the insurance despite the fact that you'd save even more if the insurance companies didn't exist.
Anyway, this is a separate problem from insurance companies investigating too much and undermining how insurance works for their own profit.
