That seems to be right in line with parent calling them advertisements.
Office 365 that is interesting because on a clean install, I still had to go to office.com to install it. I didn't have icons for Word, Excel, Powerpoint, etc. and certainly not the GBs of data already consumed by it. I'm looking at my work machine at the moment and it has an "Office" tile that I can sign in and use the web versions, but it doesn't appear to be a full Office install.
