Touche. I suppose it's because they clicked on the comments section where you read....comments. You reply to the the article or other comments - to me it's a conversation, in a way that posting a blog about why someone returned a phone isn't.
Of course it is. It's the start of conversations like this very one. Or it's a personal blog that other people find and like to read. I don't understand why the author's motivation for writing something matters literally at all, except for a small group of people who really, really get off on X-style judging/hating everything for some reason.
Perhaps some introspection would be more useful/valuable than the sneering bullshit.
Blogging has historically been about someone sharing a thought, an experience, an idea... Which this is. Why gatekeep what can or cannot be blogged about? No one is required to read or like it.
