Legal Spam

So who else got that legal SPAM :

Greetings $project Maintainer:

We currently use the $project package and we are quite pleased with it,
but our legal council has recommended that we discontinue its use. ...

And then 2 Word document with list of files, generated, test suites, etc...
missing a Copyright label. Apparently I'm not the only one, so if you got this
don't worry, you are not the only one. My answer was basically that such
issues should be made public if such legal changes was needed to an
Open Source project, I wondering how they are gonna react :-)
