In fairness, I imagine the gripe is that the three circles in Google's logo are arranged fairly similarly to the orange, grey, and pink circles in buddycloud's. Ignore the Xes and the big circle, and the logos would actually be kind of similar. That said, you may as well claim that both logos are a rip of the Olympic Games'.
There are a lot of logos out there and only so much that can reasonably be done in a limited 2D space. Of course some logos will bear some resemblance to each other. If there's one thing everyone should learn from Apple, it's that throwing a fit whenever you see a logo that reminds you of your own is silly:
They don't look that similar. The only thing they share are a set of overlapping circles, but that's just inspiration from Venn diagrams. It's not particularly distinctive.
