Personally I tried to switch many times and always made my way back, and I'm not even really in the Google ecosystem unlike others.
Anyone who has thought google was doing anything good after they bought doubleclick is living in fantasy land. They pretty much immediately started playing advertising extortion games and they optimize for more viewed google ads with things like AMP and making ads harder to notice. Google stopped caring about "information for all" the second after they made their original research paper and realized they had a significant competitive advantage to make some money with.
