I mean they aren't even scraping it (the vast majority of which is publicly available), you just buy it: regrid.com

Its far more convenient to buy parcel data from a data provider like regrid, because they do all the harmonization for you, and most county assessors offices are shit at keeping their shit straight.

And if you are cheap, it took me 15 seconds to get to this for Sonoma county: https://gis.sonomacounty.ca.gov/datasets/4b231e8ffbac47abb9a78296e550ffa1/explore?location=38.480199%2C-122.942214%2C10

Also in terms of the reactionary response.. Its all a matter of public record and is legally required to be so? Property taxes are all levied at a state/ county level, its how we fund those governments. So its disclosure is usually a legal requirement, even if the county makes it a pain in the ass (see this lawsuit involving santa clara county in California). Do a quick search for "[some county] county assessor office GIS data" and you'll almost instantly be brought to a link for parcel data for all the properties in a county.

Just.. I don't know why people think details about the structure they live in would be secret information, when the government (and quasi governmental monopolies like power companies) are legally required to both gather and make available that information.
