The logo this company (Ministry of Testing) is using:

1) The Ministry of Sound logo is imitation of an official government ministry logo anyway, eg https://www.gov.uk/government/organisations/the-office-of-th... or https://www.gov.uk/government/organisations
2) The Ministry of Sound changed their logo: http://www.underconsideration.com/brandnew/archives/new_logo...
2. Doesn't mean other people can use their "old" logo (which they're currently still using).
FWIW, I'm no fan of MOS (one of the reasons I posted is because they're notoriously litigious, even suing Spotify over the order of user playlists), but I'm also no fan of design work being so blatantly ripped off, particularly by companies that can easily afford to hand work to a real designer.
The Ministry of Sound logo is a derivative of the crowned portcullis logo of the Parliament of the UK - see https://en.wikipedia.org/wiki/Parliament_of_the_United_Kingd...
No they aren't. The MOS logo uses emblems of the British state (crown and portcullis) to create a design that's completely different from that of any British state institution, as demonstrated by your own example.
The logo of "Ministry of Testing" is not inspired by any Government emblem, it's literally just the MOS logo with one word changed and a ninja instead of a portcullis/speaker.
A company that makes $100k/month and brags about its "uber cool" design should be able to do better than that.
And people wonder why so many clients feel entitled to free creative work.
