Could you elaborate on the legality and implications of using Google icons for commercial purposes? Are there any specific guidelines or restrictions set by Google that businesses need to be aware of? Is there a licensing process involved, or are there certain types of commercial use that are prohibited? Additionally, what are the potential risks associated with unauthorized use of Google icons, and what are the consequences if a business is found to be infringing on Google's intellectual property rights? Clarifying these details would be immensely helpful for businesses considering the integration of Google icons into their commercial products or services.
