How so? Pretty much everything that Google offers has good alternatives, and there are little or no network effects except for YouTube. E.g. you can use Bing Search, OpenStreetMap/Bing Maps, Office365, Fastmail, LineageOS, AWS/Azure, Vimeo instead of the Google products. In fact, the search engine is the only product that might be significantly better than alternatives.
