We won’t be removing Element, as we mention Element specifically which uses vodozemac. The author claims that is not effected.
We don’t recommend every other matrix client which hasn’t had an audit, and we don’t believe that Matrix.org should be responsible for making sure unmaintained/hobby clients use the latest library (how could they anyway, the whole thing with decentralization). Those projects are not a part of Matrix.org and are not covered by their audits.
