I'm fairly new and don't 100% understand it yet, but instances are run on servers that require money. Are we heading towards seeing ads or subscriptions to raise funds instead of relying on donations to cover overhead?
Especially with the influx of new users. Hardware upgrades are needed.
I mean, it is possible that instance admins will be able to show advertising on ones instance, but you will be able to find dotation based, ad-free instance instead. Lemmy as a whole won't be monetized, only a particular instance. But it's only my guess
