Tbh, I think this whole thing is being blown out of proportion. Part of FOSS and the internet in general is the ability to have choice over what you use and spend your time with. Just because Sync is out, doesn't mean you can't continue to use your FOSS apps. It just means that we now have an option for people who want to pay for a very polished experience.
The reason I'm on lemmy is I WANT to use weird apps and see different things programmers do. It's like the post is telling me just get taco bell when there's a dude selling Mexican grandma style enchiladas out of a food truck and I can go over that corner restaurant and get some fire chimmi-chanagas.
I like weird stuff. So what about it? God damned people pushing some vanilla boring shit.
What I find hilarious is that the Sync dev could have simply made a $5/month subscription for the Reddit app and continued on making a fortune from Reddit's product, but instead told people to come here where there are no API costs.............and then starts charging a subscription fee and massive one off payment lol. Oh and the app also has ads if you don't pay, despite Lemmy itself not having ads lol
Just making a living from his great app. Completely fair.
You can get rid of ads with a one-time payment of 19.99$. Not a 'massive one off payment' at all. I have the subscription though cuz I want to support this fastastic app and dev.
