It does make some salient points, but it too is starting to feel a bit like astroturf.
Astroturf is created by billionaires to make it seem like a bunch of ordinary people agree with them. A legit article about several actual instances of corporations killing FOSS does not become astroturf just because a lot of ordinary people found it useful enough to post and cite.
The solution offered is not entirely clear but I read it as "do not federate with huge corporations because they will bury you".
