I feel like Swift enjoys much more actual good will and positive attention than C#. HN and other communities seem to be hell-bent on repeating the statements that weren't true even back in 2016 when it had its first FOSS version.

For example, this submission currently has 136 upvotes and 60 generally positive comments. The last .NET submission that reached frontpage had 158 upvotes and 255 comments, many of which would repeat personal experiences from 2007, complaining about products and languages that are not related to .NET but to something adjacent at best, or criticizing imagined spec and implementation issues that do not correspond to how the runtime and language actually work.

If anything, it seems like Swift can succeed if Apple puts more effort into it and community sentiment will be headwinds, not the other way around as is the case with .NET.
