2bimpressed To be honest I am not sure why you are surprised about it, as it would have been easy to find out prior buying with a little bit of research. Just for the fact alone Nothing relies heavily on Google apps and only uses a fairly limited number of their own 1st party apps like Nothing Gallery or Recorder. Even those 1st party apps and widgets sometimes rely heavily on Google services, for example Nothing calendar widgets sync with Google Calendar only, the new Nothing Warp uses Google Drive.
If you do some research, there are some topics here on the Nothing Community which help to get rid of Google apps and services as much as possible. Check out this one for example:

If you want a true Android OS without Google, you’d have to find some niche devices or options. For example Fairphone offers their products with either regular Google Android or, as an alternative, with Murena /e/OS, which doesn’t have a single Google service. Murena /e/OS/ is also available to install on existing platforms, however for Nothing phones, only the CMF Phone 1 is fully supported, while Nothing Phone 1 and 2 habe limited, untested support:

There are more known alternatives of course like LineageOS and Graphene OS. The former at least seems to officially support NP1 and NP2, the latter doesn’t seem to support at all - but I am don’t really know how these work, so you might be able to get them installed anyways.
Another option would be getting some custom ROMs which could possibly be free of Google.
