Ah.
No, I would not be happy then.
MC's website is their platform (well, one of their platforms) for communicating with their customers (and potential customers, and people who clicked the wrong link, etc.).
While their site is down, they are speechless (through it). You can host what they already had communicated, but the fact that their site is down means they cannot further communicate (again, through it).
If you are holding a sign, and I tape your mouth shut, I am still interfering with your free speech even if I start holding your sign.
