I feel like words have lost all meaning when we're calling removing a date from a blog article "hostile." It's only so for non-evergreen content, anyway. There's plenty of technical content that is just as relevant today even though it was written 2, 5, 10 years ago.
Edit for clarification: By no means am I saying that it's bad to have dates, or that we shouldn't have them. They make sense a lot of times, it's just kind of silly to call it hostile to the reader.
