You're using iCloud. Do you expect it to say "your iCloud space is filling up, buy more space on OneDrive or Google Drive here!"? My cell carrier sends me a notice every month that I need to continue paying them or I will lose service. Sure I can switch to another carrier, but if I want normal service to keep happening like it has happened in the past, I will need to send more money as per the agreement I signed. That's not an advertisement. That's a critical notification about a service you've chosen to use. It's not any different just because they offered a free trial.
