> Steam hasn't meaningfully changed in a decade

They completely rewrote their UI? Do you not remember the old library? The old downloads page? The old big picture mode? You may be suffering from selective memory

I dont care about faster startup times for steam, as long as its under a minute.

If any big company want a good steam alternative we would have it.

Every alternative launcher, uplay/ubisoft connect, origin/ea app, epic games, gog started with a store platform and stopped. Its like the marketing team just looked at the store but not at the rest of the steam features.
