I wonder... could this be the first in a line of dominos? Especially if it's the result of advice from risk analysis consultants that may be advising more than one company.
I can't understand how Ryanair could sue Siemens though, unless it was for some sort of defamation perhaps. Whatever happened to "all publicity is good publicity", though? (Yes, the clichéd line, but someone had to say it and it might as well be me.)
