The sync app dev is charging for a product. They know they have a market, albeit narrow. The income will be chunky and consistent.
The Lemmy devs provide a free platform and ask for donations. They know they have a market. It’s enormous. The income is gratuity.
Neither party should be surprised about who is raking in how much cash or why. I’m sure they’re not.
No user should be confused about why both parties are doing what they’re doing. No one should be confused about how it’s going for them. But for some reason y’all won’t stfu about it.
