I can understand not providing general updates after ten years, things like QOL or features, but security updates should be provided much longer. That goes for mobile OSes too. My phone is not receiving them after 5 years, and being a flagship when bought it’s still a banger, 8 Gb RAM, 8K video, good screen, good camera, 5G, etc… The lack of updates is making me look into alternative ROMs, but the general population isn’t capable of doing that.
