If it is trust based i would rather trust someone who's open source and privacy advocate than any corporation that will abuse the data as soon as it is profitable for them. but that is my choice that follows my priorities.

Even more so when company - in the cited examples - already has heavy conflict of interest when it comes to service provided(chrome tracking <-> google ads feedback loop that gives them even higher unfair advantage)
