We are currently working on a countermeasure. In particular  we wonder how
reducing from eight to four entry nodes would effect the bitcoin network.
We also think to decay the connections based on the number of transactions
(for example  renewing half of the entry node connections after each
transaction). It might be interesting to include a proof of work for
creation of connections, but this would create a compatibility issue.

Excellent!

I've been accused in the past of "not caring about privacy" -- when I do care a lot about privacy. But I am not a privacy researcher, and I have a deep respect for how difficult it is to create a truly privacy-preserving system.

I'm very happy that somebody who is an expert is thinking about, and working on, countermeasures.
