The default sms app showed me advertisements that seemed way too sophisticated for a medium like SMS or MMS. I had to disable a setting called "RCS Chat" to rid myself of that nonsense. I am pretty sure it isn't something that Google invented or something like that though so I'm not comfortable putting the blame squarely on them for it.

RCS is absolutely awful as it displays banner ads in your notifications. The notifications are far worse than what you get with SMS. It's the reason I turned off RCS as well.
