Come on, your second example is silly at best. You are seriously saying that the middle O in their Google logo has bad contrast, and therefore they don't care about accessibility?

And your first example doesn't even mention that there is a specially designed high-contrast mode for android which fixes the readability issues for those who need it, and Chrome has a text scaling option which can increase the font size and will actually wrap in the way you want, and android itself has a "large text mode" which will achieve much of the same.

Google isn't perfect, but those examples aren't exactly doing you any favors trying to show the issues.
