That's misinterpreting what the previous poster is saying. They are saying that hyperscalers owning significant portions of the Internet (and using lots of projects without giving back) is a bigger threat to the sustainability of OSS.

Now I would argue that the sustainability of OSS is more important at least in the context of an lwn article. That doesn't mean one can not argue that rug pulls are the bigger threat, but that's not what you accused the previous poster off.
