No people didn’t choose to have Microsoft. Microsoft forced OEMs to bundle Windows with all of their computers. Even if the OEM decided not to bundle Windows, they still had to pay a license fee.

No personal computer comes with Chrome installed by default unless the OEM made a deal with Google to bundle it along with other crapware. Users have to explicitly download Chrome.

It’s a lot easier to change your default search engine than change your operating system.

The proof is in Google’s dominance. Google became popular when IE was the default browser on PCs and Safari was the default browser on Macs.
