Unity did predict this will happen, their blog says: https://blog.unity.com/news/welcome-ironsource
"While Unity’s and ironSource’s management believe the assumptions underlying the forward-looking statements are reasonable, such information is necessarily subject to uncertainties and may involve certain risks, many of which are difficult to predict and are beyond management’s control. These risks and uncertainties include, but are not limited to the expected timing and likelihood of completion of the proposed transaction, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the proposed transaction; the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement;"
This is why we know Unity and Ironsource will keep going on with the plans, Unity knows the problem and Unity did not care about the past behaviors until something bad happens. This is why everyone is saying to uninstall Unity because something bad will happen.
