Half of those instances is people just being resistant to change and wanting things to be how they were, as opposed to being particularly attached to the type of content itself.
Oh, the poor darlings.
If they want to broaden their appeal, you can be unhappy and you can say so, but really you're just going to have to deal with it. Why should they toil away for a small fanbase when they've got mortgages to pay and kids to feed, or even just want another Ferrarri to add to their collection? They aren't your slaves. And besides, creators create - few want to be stuck doing the same stuff year after year. They grow, experience, develop, innovate.The other half is people rightfully reacting to devs trying to "appeal to a broader audience" by compromising what they feel is a central element of a franchise. Such an attitude is always wrong, it was wrong when it caused em to westernize Jrpgs in the 2010s, with the infamous star ocean 4's usa version cutting out the gorgeous handdrawn artwork for the chars in menus and replacing it with the ingame models, and it's wrong in this way too.
The world moves on. Preserving things in aspic is just stagnation. Either move with progress, or become like an aged grumpster waving his walking stick at newfangled stuff and damn kids, in addled confusion. Or as the saying goes, "a reed that doesn't bend in the wind, breaks".
