It isn't the "goodness of their hearts", Nvidia just wants to maintain their position as the market leader in the markets that will be there for a long time. Gamers is one such market. Some gamers are loyal to a particular brand of graphics card, but there are also just network effects to being the most popular. Game designers spend extra effort making sure their games work well on the most popular video cards. Influential people like YouTubers, streamers, or game reviewers are more likely to buy elite hardware and talk about what they got.
Market segmentation would only really make sense if Nvidia were capable of saturating all the demand from miners, and wanted to squeeze out some extra margin from them. But right now it doesn't seem like Nvidia is actually able to manufacture enough to meet the market demand at $800 like they initially intended.
