I don't see the same thing here. Google isn't making any money from being the assistant in Apple, so why would they pay to be it?
I guarantee you Google will start letting people pay to influence the output of the Gemini models once they figure out how to do it.
smart is a weird term, gemma4 is an amazing omni model better than qwen3.6 for non coding tasks (as for all Gemini models). For Apple Intelligence gemma4 makes a lot more sense.
