That's pretty ridiculous. If Microsoft complained about this I would lose a lot of respect for them. This doesn't threaten linked in whatsoever. What other names can't be used because linked in exists? The possibilities are endless.

They already have complained about a similar thing: https://en.m.wikipedia.org/wiki/Microsoft_v._MikeRoweSoft

Ridiculous? It seems that you are not familiar with "trademark likelihood of confusion" and similar concepts (see the U.S. Trademark Act, especially 15 U.S.C. §1052).

It's anecdotal but I wasn't confused at all.
