On a personal level if I used to do 100 google searches on a daily basis, now I would be doing only 10. And it is the case with everyone in the tech ecosystem at least. So it would be fair to assume that there share has reduced.

On the LLM side as well, I have not seen much people using Gemini vs the market share of Claude / Open AI.

The assumption of the long tail still using Gemini because it is bundled might be correct, but I am not even sure if that is something that Google will be happy with.
