It's a semi-smug affirmation that you don't care which, great. There's others that do, especially when the trajectory for changes like these is for a platform to get worse, not better.
I agree that it's a pattern that happens a lot on unrelated threads, and it sucks, but this one in particular is an exception since the entire OP is about trying to make us care.
The point of the article isn't to make you care about Bandcamp in particular, though it's clear the author does. It's to point out the fact that if there is something you DO care about, how acquisitions and corporate plays can and will destroy it. You could replace Bandcamp with Steam, or HN or any other entity. That's the point. Not the particulars of Bandcamp itself.
People here get so lost in the weeds and don't actually read what the message of the article is.
Bandcamp has lasted because they haven't let the place go to shit like their competition and they've been reliable enough to stay online consistently.
I don't need social tie ins, and I don't want to message my listener base about anything. The spam emails I get from labels trying to be social go directly into the trash and usually make me unfollow them (or disable notifications)
To put it another way, there are plenty of ways to find music, what underground musicians need is a an easy to use tool to put their music online, as we are not big enough for Spotify.
