Re: Ignoring the sex for a moment
I work in medical stuff for a PLC.
There are memos every day about what can and can't be said publicly without there being an official stock market announcement. There are vastly more complex rules about confidentiality of data. We even had to change email provider because the previous one had servers in the USA and the lawyers decided that if an email went through American wires then a whole new set of HIPAA rules would apply.
Then there is a different set of rules about patents and who things can be discussed with at different filing stages of a filing. We even have a pet lawyer sit in on some meetings so that they can be claimed as privileged during discovery.
If some judge has just determined that all point-point electronic communications are "public" then the whole medical/financial/defence industries are going to have to go back to quill pens.
