I expected the other side of this link to be a thinkpiece that maybe having one company host and track all of our blog reading activity isn't smart in a post-Cambridge Analytica world (or even a post-Snowden world, but whatever).

It’s actually saying that maybe giving a company control over your own blog isn’t always so smart. True.

For these reasons it seems dumb to me that Mastodon itself (not the author of this post on mastodon) blogs on Medium. Like a global warming activist jetting around a lot, it just shows one not putting their money where their mouth is.
