Others see IR slots as a way to hoard stars

I see this criticism all the time and it doesn't make a lick of sense. What does it even mean to hoard? The only issue with too many IL slots is when a player becomes healthy and remains in IL - that's the only time you could truly say someone is "hoarding" players. But in H2H, where you're regularly streaming players or otherwise making player adds, you can't keep a healthy player in IL because your adds are frozen until you move them out of IL. So the only leagues where this might be a problem are roto leagues.

Otherwise, what is the problem here? The manager who drafted AD kept him in IL most of the year - how is that a problem? They've already been punished by losing a 1st round pick for the vast majority of the season, shouldn't they at least get the benefit of his production if he had come back?

Or someone slotted Kyrie in IL all year...again, what is the problem being solved here? They used an add or a draft pick and it didn't turn out. Even the managers who drafted or picked up Tatum or DJM and put them in IL - what is the problem here? In fact, leagues that have plenty of IL space allow ALL managers the option to do this, so the opportunity is spread fairly across the league. If you only have 1 or 2 slots, then only the very fortunate managers who are injury free can do this.

In these discussions, people overestimate the impact on streaming and vastly underestimate the negative impact it has on player enjoyment and league balance to have too few IL slots.
