The usage of Whatsapp is not affected and it can run normally without Google Play.

As you may know, Whatsapp does force users to upgrade to new version every few months. This is the only time you may need to re-enable the Google Play Store for a short while for the Whatsapp installation, and then disable it again after the installation is completed.

Alternatively, you can download the official apk file from Whatsapp's website directly and install it manually. This is the way I am doing.

whatsapp does use google service like the backup function for example . it backup your chat history and media to google drive and without google serice that function is not possible . also for update there is probably oak os equivalent of play store but facebook putting whatsapp there is unlikely either because it bans all company not only google to use huaweu
