That's because they have all become a commodity, nothing new or interesting is out there in smartphone land.
The existing photos stay at full quality. After 2020 any new photos will be at lower quality. Your existing photo quality isn't downgraded. By that time the software support has also expired and the owners will already have bought newer phones.
Terrible display? It lacks the eye candy (and side damage prone) edge display, but curious your thoughts as to why it is bad otherwise. Since you apparently have reviewed it yourself, I am curious how a display with a higher pixel density than the Note 8 could be considered grainy (you mentioned that in an earlier post) ?
TBF, hardware manufacturing was always a cut throat business. Customers free updates for life, but updates cost money. It should be a given that if you buy a low end phone, you shouldn't expect much support from it. Seriously, are people still genuinely surprised that an Android phone with a MSRP of $50 to $200 gets so very few updates? Iphones getting 4 to 5 years isn't much when a decent number of folks don't go beyond 1 to 2 major updates that it originally supported, citing concerns of performance hits.
