Yes, any advertising in the base operating system is totally unacceptable since it means the OS is tailored to the needs of the advertiser instead of those of the user. The base operating system - that is everything needed to run the system as normal without compromising on functionality - should be a clean slate as far as advertising, and 'telemetry'/user data exfiltration is concerned. If a user wants to install anything on top of that base system which comes with advertising that is his choice but the base should be ad-free.
