It’s a bit overblown IMO. Unless you’re going wild with multi material it’s about the same as any other printer. Sure it purges a little even if you don’t change filament between prints but it’s still such a small amount. I found myself purging a little each time with my Prusa and Enders before too.
If you’re that worried don’t get an ams for multi color printing. Get an ams to reduce waste for automatic spool runout switching.
Should go after anywhere that has perpetual agreements including the ones that try to get around it by the last living clause or 100 years etc. I don’t know a good solution but I’m sure they can put limits and carve outs where needed.
