> Yes, they entered the market around those years, but what does that change?

It means the hardware was purchased after it started to be discontinued.

It's hardly a reasonable take, and makes little sense, to complain how you can't upgrade hardware that was already being discontinued before you bought it.

> DDR3 and LGA1150 were not deemed "legacy" the day DDR4 and LGA1151 motherboards entered the market.

I googled for LGA1150 before I posted the message, and one of the first search results is a post on Linux tech tips dating way back to 2015 on whether LGA1150 was already dead.

And you purchased the Mobo one year after that.

I think you are forgetting the context of my replies. I'm not saying it's unreasonable to have to upgrade discontinued hardware, even if you have to do it all at once. My take is that it's not too different from having to replace a Mac when the new generation comes in (which is usually every ~5 years for Apple, not too far from my own system's lifetime). Being able to upgrade individual parts through generations is a pipe dream.

Also, we must have a different interpretation of "discontinued", because DDR3 and LGA1150 were still produced, sold, and dominated sales for way long after I bought that system. At the time (and for the next 1-2 years), consumer DDR4 was a luxury component that most no existing hardware supported.
