Re: The damage is done
They are not particularly reasonable. They create a new problem (per-install fees), they come up with their own solution (DRM which the developer doesn't have any insight into), and they say to the developer "we're going to charge you this, trust us on this".
How does it deal with uninstalls? Computers not being used for months? Hard drives dying, being changed then a new install? Android app storage being cleared? Nobody knows.
If end customers have a licence to use their purchase on five devices as is usual now, they should just be more honest and raise their fee from x% of developer revenue on a game to y% from Unity 2024 onwards. That way the developer isn't trying to work out if they can afford the pricepoint vs average number of installs. There will be people grumbling of course but it still wouldn't be the mess we've just seen.
