Microsoft's compliance is largely to allow for Bing to be removed as their built-in search, and ability to uninstall Edge. They are also only allowing this within the EU market, not globally.
Google just needs to allow for the selection of a default browser, provide links in Google search to competing sites (which Google will still make money off of with their ad delivery network anyway), opt-out option for sharing data between YT, Search, Maps, etc. As well as allow outside payment processors for apps.
For Microsoft and Google, none of these changes are affecting their cash cow. Cloud computing for MS, and ads for Google.
These DMA changes are affecting Apple's cash cow, the iPhone. and their second largest cash cow, Services and IAP. Apple has a LOT more on the line with these DMA changes than MS or Google do.
