From the European Commission fact sheet (Emphasis theirs):

The Commission’s investigation showed that Google obliges manufacturers, who wish to pre-install Google’s app store for Android, Play Store, on their devices, to also pre-install Google Search, and set it as the default search provider on those devices. In addition, manufacturers who wish to pre-install Google’s Play Store or Search, also have to pre-install Google’s Chrome browser. Thereby, Google has ensured that Google Search and Google Chrome are pre-installed on the significant majority of devices sold in the EEA.

And:

Google’s conduct has had a direct impact on consumers, as it has denied them access to innovative smart mobile devices based on alternative, potentially superior, versions of the Android operating system. The Commission has found evidence that Google’s conduct prevented manufacturers from selling smart mobile devices based on a competing Android fork which had the potential of becoming a credible alternative to the Google Android operating system. In doing so, Google has also closed off an important way for its competitors to introduce apps and services, in particular general search services, which could be pre-installed on Android forks.

And:

Google has granted significant financial incentives to some of the largest smartphone and tablet manufacturers as well as mobile network operators on condition that they exclusively pre-install Google Search on their devices.

The letter was also sent to Alphabet, as Google’s parent company.
