I am a software developer, I understand what goes into developing software. He is allowed to value his work at whatever he thinks it's worth.

But as users we are allowed to think he is asking too much or pushing too many ads or whatever. It's not disrespect, it's an opinion, about a mobile app that now has ads on the main feed and in every comment section, that only works based on a platform that is very specifically known for being open and not pushing ads. And it's an especially high price for an app that is still very under development and has only recently just gotten an update for the first time in months, even when some features had stopped working.

I have no issues with him asking to be compensated for his work, and I am glad he makes it available for free, but the ads are getting intrusive, and we are all entitled to our opinions. I don't think there was anything disrespectful about the way I shared my opinion, but I do think it's crap to tell us we are being disrespectful just because you don't share that opinion.
