I have a Pixel 2XL. It's in perfect condition, works well, and still has decent battery life on the original battery. It has no problems running everything I use, and there would be little benefit I would gain from getting a new phone. Yet Google dropped security updates at the end of 2020, as with the 3a, three years after launch, and around a year after they stopped selling them. My phone now nags me to buy a new one in the settings. Now, it might be argued that Google has no obligation to produce updates for their products, but... if I try to improve security on the phone by using third-party distributions that are updated, rather than buying a new phone, then thanks to Google's SafetyNet, the phone will be crippled and have difficulty running many banking, payment, and other apps that are at this point a requirement in many situations. Thus, the reason the phone is problematic at this point is because of Google's working to make the phone unusable, not just the lack of updates. It is bizarre that SafetyNet will vouch for the security of an OS Google itself argues to me is unsafe because of lack of updates, while not allowing a third-party distribution. Yet I suppose I wouldn't be surprised if Google eventually decides to have SafetyNet stop functioning entirely on older devices, in the name of security, to make them even less usable.
