I think it's important to recognize that you or I may not be the ones at risk here, and the same convenience/safety tools that we don't think much about might have an outside impact on others. I was in a fancy managed apartment for a while and they had carded access, security cams, electronic package lockers, etc. That relationship is pretty unique in that I'm paying a lot of money for a more "luxury" experience, and I have more leverage if something goes awry. (This management company totally dropped the ball on making the actual units nice to live in, but that's another story...)

There are plenty of horror stories of landlords being shady, the classic one being coming up with an excuse to hold the security deposit. I really would not trust them with putting "smart" devices in my home. I once rented in a complex where the online credit card payment cost an additional $15 fee over walking to the office and handing over a check, because it was some service that they bought in that skimmed off the top. Rent-to-own also has a history of being predatory towards people with lower income. On top of the typically terrible value of renting to own, it's the same relationship as renting where a bad landlord could do all sorts of things, but now you have even more to lose since your money is locked up in the relationship.
