Interesting point. As far as I know, it's not that easy. We have a client who contacted the owners of the website he needs to scrape and offered to pay them for access to their data but they were not interested. I know that they are not their competitor and they're not doing anything that would harm their revenue in any way. I assume that they figured it was not worth the legal, organisational and other formal hassle to share their data.

Let's say that we want to pursue this idea anyway. We would have to reach our to every website owner that our clients scrape and figure out how to share the revenue. You cannot just transfer your money to another company. You need to sign a contract and in many cases have it approved by legal and compliance teams.
