For me is the contrary. I know from who I will not buy a game, ever.
Many people do not buy games for a lot of random reasons. A developer who only complains will never get my sympathy (and Jools, where is Treasurenauts?)
Good thing then that CSH's developer doesn't only complain, the dev has always been great with engaging the audience of their games as well as taking feedback in stride. The comments made were obviously meant as a casual discussion about their personal frustrations and not meant to be a PR statement or interview about their grievances and it sucks that only specific quotes were used without context of the overall conversation to represent it as overtly negative about a specific platform.
If developers, especially indie ones, don't feel free to be able to discuss their concerns or issues without it seeming like it's an attack on a platform then it makes it more difficult for that platform to get feedback to make improvements which benefit everyone. Hell back in the Xbox Live Indie Games days they had a public board for developers who were pretty frank about submission issues or technical problems and those were welcomed.
