all of them have one part thats like really famous. mac, android, webpack and bluesky are all things everyone on here knows about so anyone making jokes would get laughed out as ignorant.
the only ones that dont fit in are kobo where it was explained in the title (the full name is "Instapaper is now on Rakuten Kobo e-readers"), and the testflight one is obvious because the title mentioned iOS.
bitchat, radicle, gleam and tangled are newer and came from the community based hacker side instead of the commercial one where big tech and vcs live. if your project has zero marketing budget of course there will be some people who never heard of it.
Radicle and Bitchat have been covered here quite a few times. These drive-by commenters (all making the same joke) come every time, and they think they’re being clever by discouraging people from looking into the product.
Note that you’ll never hear people saying “what’s a Google” (an equally ridiculous name) or jumping on some random YC startup with a silly name. It’s always the open source tech. It’s not random!
Joke’s on them anyway, I believe many users have embraced the alternate interpretation of the name. There’s a @BitchatMe_ Twitter account that covers BitChat news, for example. They’re just being annoying without any real effect.
