I didn't upgrade since 2013, and since getting my new phone I found no new features important or even that useful. Having more memory allowed me to download more. Bigger screen doesn't fit in the pocket. Features like split screen or shake twice for the camera ti show up or the new ways to lock and unlock your phone don't really matter.
Being able to chose not to use google is a luxury here. Therefor google is a monopoly for these low income people and also a utility since having a phone and the services that come with it are essential.
My intuition is this is not a meaningful factor for a locally-focused business.
Right now it would be completely within googles right to block an individual from using youtube at all. You would have no legal recourse against this and it would massively impact your life. Almost all video on the web is on youtube. Even government information videos are hosted on youtube now as well as countless general information videos and health/safety videos.
It's pretty easy to make a case that everyone should have a right to watch videos on youtube because of how important the content on youtube is. This is what making google a utility means. If some random forum bans you, you get on with your life. If Google does something it can have serious impacts on your life where you have no options for alternatives.
These phones all run android or have no features which are required in the modern age. The OP point is that avoiding google is a privilege many do not have.

Your competitors are advertising on facebook and google. If you want to compete you have no choice but to do both.
