I don't know how much people know or have heard about ironSource. It's kind of an open secret in Israel on how they built a company to profit by building what is essentially malware (installers disguised as OEM while they're really adding extra trackers to your computer). They always paid 25% more than most of the other tech companies, but still had issues recruiting because it takes a special kind of person to be willing to do these kinds of things
I didn't really understand the merger when it happened, but I have no doubt all these new policies are a result of the ironSource people integrating into Unity
