I actually agree with you on this (having ads in a community full of supporters of open source and anti-capitalism is a bad idea), but I think the dev has already run the number and decides going with ad-supported model and $20 permanent ad-removal IAP is the only way to make enough profit to sustain full-time development given (currently) low number of lemmy users right now (100,000 active users is too small market to profitably sell $3 apps). I subscribed to sync ultra to support the dev, and hopefully if the dev is able to sustain himself from subscriptions, he might be more open to removing ads in the free version later.
