I don't use gmail because why would anyone want to use gmail for anything but temporary throwaways that'll get spammed.
I don't use google maps. nokia heremaps and openstreetmap (I use magic earth) are better in most ways, worse in others. When I go to a different country, I click "download country" and have a fully searchable map. No, I don't want a map that needs a data connection. No, I don't want to have to visually search the map for the thing I'm looking for, because someone barfed up a salad of dots that are place ads for things unrelated to my search. Google maps is not usable to anyone who has used something else. People who always use google maps don't know any better.
I do use google translate. This does not support your argument, because that's a service that is free, and does not display ads. You saying that the current ad-free service will disappear if ads were blocked from it... Can't make the comment on here that I want to make, so I'll let you imagine <words>
Youtube... Who give a crap. There were sites with videos before, there are other sites now. No, no one can host a huge expensive platform like that for free. So how about the people posting stuff, pay for their stuff being hosted. Then those people can inline talking ads or put a coke can on their desk, in their videos. You know, how ads in videos have been done since the existence of the video format, in 1920 all the way up to right now.
Google products, google customer service, and google the company, are inferior to the competition in almost every way. Except for google translate. Which again - has no ads.
