And this is why when Pixel phones started promising 7 years of support, everyone with a brain said “uh huh, suuuure” and kept buying iPhones which DO deliver that.
I guess we will see by October 2030. They'd be getting a class action lawsuit for clear fake marketing.

It doesn't seem like they are ending support for updated software on these devices before 10 years, it will just be different software.
So far so good for the rest of us without brains. Pixel 6 got it's full 5 years of promised support. We're hoping it's cheaper to provide the full promised 7 years of support than to pay the class action lawyers.
