I'm not saying I'm entitled to anything, I'm not asking for anything. I don't want to use sync for free, because there are tons of other free lemmy apps as well as the regular Web lemmy that are all free and without ads (I guess all those apps created themselves for free right)

I'm telling the OP to fuck off for making a post commanding people to buy premium time.

Do you think sync devs are entitled because they the actual content from lemmy for free, stuff their own ads in their to make money from it?

Get a grip dude. Throwing a tantrum isn't going to get me to spend money on that app. Nor respect someone making something worse with ads to try and coerce people into paying for it.
