Put it simply I just hate ads. Anything that puts in ads is terrible. Including Sync for Lemmy who seems to have completely missed the point of getting the hell away from Reddit.
The next terrible thing is automatically generated content and bots, but I guess those are also really just ads.
That isn't a good justification to me. If it's ok for you then it's ok for the rest of the world too. You might believe ads aren't bad and that's fine. At least we can agree to disagree on that as our opinions aren't reconcilable. If your app can't exist without ads then I don't believe it should exist at all. Or any other software in the world.
