Re: Kneejerk canned response
The "something we take very seriously" line is, as you say, meaningless in itself, but in context it does have value. It's a license to journalists to follow up the issue and ask more questions another day.
Most public figures are happy to give out such licenses, because they know (a) journalists are lazy and there's a good chance they won't bother, and relatedly (b) the public attention span will have forgotten all about it by tomorrow, so any attempt to follow up will have to start with a recap, meaning most readers will have switched off before they get to the new bit.
