It was released three years ago, which is the date you should use for figuring out the life span of a device. You should expect to get less time out of a phone that's already been out for a year and a half when you buy it.
In my country a used 1st generation Pixel can be had for less than the 5x was when it came out (~$300 vs $379). It's not ideal to have to buy used instead of new but it is doable. The Nokia appears to cost about the same price that the 5x did but im not sure it's easily available everywhere.
Anyways, your situation is unfortunate but I don't consider Google's actions to be egregious in this instance.
