I happen to own, or previously owned a grand total of five devices listed on the pirg page. While I fully agree that taking away cloud support from devices that require that functionality really sucks, but discontinuing software updates after 8+ years like in the cases of iPhone 6?!? As far as I concern, that’s in the “you gotta be kidding” category.
To be specific, of the listed devices I have or had the Moto G2, G3, and G4, and I didn’t find the Android updates particularly useful, especially with regards to functionality. The G2 came with Android 5 and with that I could tether the phone on Cricket (AT&T) and utilize my "unlimited’ data. However, once it received the *forced* update to Android 6, tethering would no longer work without paying some extra for that feature. 🙁
All 3 phones were later obsoleted by AT&T requiring “HD voice” ( https://www.att.com/support/article/wireless/KM1046244 ). However, the G4 still works fine with a LycaTel (T-Mobile) SIM.
In comparison, I’ve had some Motorola StarTAC phones before (TDMA and GSM) and for most people. there were no such thing as software updates.
