As others have said I think the title was more clickbait-y. Olaf was the person who wrote the in-kernel NFS server so I think he at least appreciated NFS somewhat. The paper makes a few reasonable criticisms many of which are addressed now.

My favorite criticism from that paper is that NFS clients reused the source port so that the server can detect whether a new connection is the same client or not. This confuses stateful packet filtering on the network because both connections now have the same 5-tuple and packets on the new connection can look like out of window packets on the old connection. This can get connections blackholed depending on the network. This was fixed a few years ago in the Linux client for NFS v4.1, since that version of the protocol already has a different way to identify clients. Before this was fixed, EFS had to document a workaround.
