Given the very large user base of professionals for AD, if Renesas makes great and dependable libraries for all of their parts (which they probably will), this has a good chance of getting many more customers.
But yeah, nothing of that kind is ever guaranteed, and this is a fricking large amount of money. Completely crazy. Such an investment would be already massive for getting, say, their own foundries, but for just a software? We'll see. Not really my problem I must admit.
I just don't like this seemingly neverending concentration of power. I think there should be economic rules to force a company to split up into smaller ones if it reaches a certain valuation. It would be a simple and effective way of fighting this concentration. Of course that may not be everyone's opinion, and some may argue that concentrating companies makes the whole more efficient (if that was the only thing to consider here), which I actually highly doubt anyway.
