I may be in the minority, but I do feel like that is teaching people the wrong lesson. People should be thinking before they post and treating this like an open public square. It was one of the first rules of the internet back when it started. People can easily create throw away accounts for questions they are uneasy about a question.
One of the things reddit still has on the fediverse is that they are a repository of free knowledge. If this place is treated like snapchat or instagram stories, then it may never really grow.
Also if the idea is that everything gets purged every year or so because people’s instances can’t handle the data, that’s also fine, but it should be something we become aware is just the culture of the fediverse.
I do think if that becomes the culture, that people would be less likely inclined to interact, post and try to build something that can easily just be taken down. This topic comes up often enough that it does seem to worry people.
