To be fair that % of revenue Unity was historically getting from most of its customer that were actually making meaningful amounts of money (i.e. enough to have a permanent paid workforce) relative to the value it provides (especially compared to Apple's 30%) was very low. Of course not surprising given how relatively little pricing power it always had.

But I don't really buy the pricing argument. Most of that type of games are all made with Unity meaning that it wouldn't be too hard for all of them to raise prices by a few % with minimal impact. That mostly only applies to IAP not to ads but then again Unity was offering a discount/waiving the fee if you were using their platform (which is of course scummy and predatory but probably wouldn't have had a massive financial impact).

Overall yeah... they completely messed up with aligning their pricing model with their long term goals as a company. It was always highly suboptimal (the per seat license is almost insignificant for some companies while a significant barrier for smaller ones, contractors etc). They would probably still have been fine if they hadn't started almost literally burning money like complete madmen after the IPO for no reason. Instead they now have >$2 billion in debt (albeit low/zero interest) and nothing to show for it whatsoever (well besides IronSource to some extent I guess..) in addition to a still extremely bloated but also unproductive and heavily demoralized workforce.
